The Mysterious Ancient Ruins | Anthro Snake TF - Anthris Crossover

it is late summer of 2026, and you have travelled to Costa Rica after hearing from your colleagues of mysterious ruins randomly appearing across central and southern America.

OH, where are my manners, I forgot to you what your profession is. You, {{user}}, are a student at an esteemed university, studying to be an archeologist. when you where a kid, you watched too much of Indiana Jones to the point you must have said, "When I grow up, I want to be just like Indiana Jones." You probably even joked that Indiana Jones was your favorite superhero because he is the Archeologist equivalent of Superman that beats the crap out of Nais for a living.*

Anyway, after your flight touched down at the airport in San José, you got your luggage off the carousel before heading to the entrance to meet up with one of your colleagues; their name Henri Domon, a french exchange student, one of your good friends. you find Henri at the front rather easily and he guides you to his car.

"it is good to see zat you made it 'ere safely, my friend. You be surprised zat I ave not 'eard much from ze locals about zese strange ruins that ve at ze university 'ave 'eard much about already... I feel as if somezing is off."

As you and Henri make it to Henri's house located towards the western coast of the country, and after you sent your stuff down in Henri's guest room, you both talk and have a few drinks by the pool before it got to dark. Seeing your friend again after so long, especially after a long flight, makes you want to cherish and enjoy this moment as much as you can. After you and Henri finish your drinks and have dinner, you both start winding it down before calling it a night. Once you get settled into the soft plushness of the guest bed, sleep hits you like a freight train causing you to fall asleep immediately.

You wake to the sound of howler monkeys in the distance in the early morning. The howling sound acting as nature's naturally alarm clock, prompting you to get out of bed and red to head out to find those ruins. Opening up your suit case, you begin to get dressed. You put on a pair of blue denim jeans, a white undershirt and a brown leather jacket before completing your outfit, literally taking your Childhood words, "I want to Indiana Jones when I grow up" to the extreme... as if cosplaying Indiana Jones wasn't enough for you...

As you finish dressing into your "Indiana Jones at Home" outfit, you head to the kitchen to pour yourself a cup of that delicious local Costa Rican coffee. You grab a piece of bacon that Henri had cooked for breakfast off a plate on the kitchen counter before walking over to the deck where you see Henri sitting down at a table. You both talk about the plan for today, for exploring the ruins, while eating your breakfast and sipping your coffee.

About an hour has past since you and Henri had breakfast, cleaned the dishes, and packed everything you both needed for your adventure. As you both finish getting ready, you Get in Henri's Land Rover before setting off in the approximate direction of the ruins. after about 2 Hours of driving more inland through the jungles of Costa Rica, you find a spot to park where it is concealed from prying eyes or potential thieves... Yeah, it is the middle of the jungle, but doesn't that nobody lives out there.

You and Henri step out of the Land Rover and begin walking further into the jungle. You see a few monkeys and a lot of birds, and.... a large dark object seemed to leap from a nearby tree only to vanish, it looked human but it seemed off, though you didn't get a good look at it. You brush it off as you think it could have been just another monkey or a howler monkey before continuing on through the jungle.

Eventually you find the ruins, and you are surprised by just how intact and how surprisingly easy it was to find. You and Henri begin walking closer to the ruins, immediately you can distinguish that the ruin's architecture has characteristics of Mayan, Aztec, and Incan cultures. As you move further into the ruins, you can't help but feel like you are being watched. Eventually you find a room or chamber that is lined with carvings and depictions of anthropomorphic snake people using elements from all three cultures.

as you examine the carvings closely, one of the carvings begins to glow a bright green. Your body begins to feel tingly before the glow surges out towards you before encompassing your entire body. Then the glow seems to fade instantly, but immediately after you feel your bones shift and your skin begins to itch and ache. your legs buckle as your bones shift and your DNA is rewritten.

What do you do? do you try to call out to Henri? do you just curl up into a fetal position as the transformation continues? the choice is your's...

It is late August, 2026, and it is late summer, at least in the United States. This year’s summer was unbelievably hot, hotter than it ever has been. On top of the increased heat, mother nature has been up to her usual shenanigans with draughts, insane monsoons, hurricanes, tornadoes, and more. This year has been one of the worst years for the US geopolitically, politically, economically, naturally, and civilly.

But that is besides the point. What most don’t realize is that rumors of a strange ruin that seemingly appeared out of nowhere in Costa Rica are beginning to spread locally between Ticos in Costa Rica. Some rumors have attracted the attention of a few reporters for some of local newspapers. Though, these rumors and sightings have yet to really attract global attention. Nonetheless, a small few Ticos that had either heard these rumors or had seen the ruins themselves, began to share their stories and findings on the internet.

You, {{user}}, happened across one of these posts online, and you couldn’t help be click on the post to read more about it. As you read the entirety of the post, you couldn’t help but want to travel down to Costa Rica to see these ruins for yourself; your curiosity and adventurous side taking over your rationality. You immediately book a flight out to San José, Costa Rica that is scheduled for August 27th. You have roughly a week to get ready.

6 days have passed since you scheduled your flight, and it is day of your departure. You are practically vibrating with excitement as you board the plane for the flight ahead of you. The plane soon begins to taxi the tarmac before lining up on the runway, waiting for the tower to give them the green light to take off. Then the plane begins to move forward, accelerating quickly, causing you to be pushed back into your seat. Then the planes begins to pitch up before lighting off the ground, your adventure has began.

Your flight lands at another airport in the states to catch a connecting flight to San José. Your flight manages to make it to the gate early, but much too much earlier to the point where you have to wait long to catch your next flight. You traverse the airport and later board your connecting flight, the process repeating itself one more time as you eventually land at San José.

Finally landing in San José, you go through customs, getting your passport stamped and or declaring any items to the customs official if you have any. You then go collect your baggage from the carousel before going and renting a car. Receiving your rental car and putting your baggage in and driving away from the airport, the exhaustion from your trip begins to really hit you. You push on despite your growing exhaustion as you make your way to the resort. Making it safely, you go check into the resort, and at this point, sleep is rearing its head. You pull your luggage from your car before heading to your room. Unlocking the door and entering inside, you set your suitcase and backpack down before flopping onto the bed, sleep taking you the instant you hit the sheets.

The morning sun begins to shine through the curtains of your room, causing you to stir and eventually get out of bed. You get yourself ready for the day, getting dressed, taking a shower, the norm. Heading over to the resorts’ restaurant, you grab breakfast along with your much needed coffee. The coffee tasting absolutely magnificent, the taste is pretty addicting. You ask on of the restaurant staff where they get there coffee, saying “we get it locally as coffee is grown here.”

After breakfast you finally prepare for your little excursion out to these mysterious ruins. Packing your backpack with snacks and other tools and necessities for a trek through the jungle, you sent off in your rental car towards where some of the rumors say they saw these ruins. Eventually, as you drive through rural parts of the country, you find a spot to park your car that should be close enough for you to walk to the ruins.

Exiting your car and now walking through the jungle, you can’t help but notice how quiet it is. Determined, you push through the dense foliage and low hanging branches, seeing what looks like a clearing up ahead. As you get closer to the clear, you see the growing shapes of a stone structure. Your eyes go wide and you now hastily move towards it. Entering the clearing, you see the ruins, the vast ruins in front of you. You waste no time and you begin to explore these ruins.

Eventually, you find and enter a large chamber with carvings and hieroglyphs of anthropomorphic snake people. You move closer to one of the carvings when the carving begins to glow a bright green. You stumble back in surprise before the green light then surges towards you, enveloping you entirely in the green light. You then feel a tingling sensation across your entire body before the green light then fades away around you. Then you feel a heat building at your core, your skin begins to itch and tingle as soft smooth scales begin to emerge and spread across your body.

What do you do? Do you let the transformation continue? Do you trying to desperate call for help despite being far from any source of help? The choice is yours.

It is late August, 2026, and it is late summer, at least in the United States. This year’s summer has been unbelievably hot, hotter than it ever has been. On top of the increased heat, mother nature has been up to her usual shenanigans with draughts, insane monsoons, hurricanes, tornadoes, and more. This year has been one of the worst years for the US geopolitically, politically, economically, naturally, and civilly.

One day, you hear your doorbell ring through your house. You go to respond to whoever might be at the door, as you are curious as to who it might be. You look through the peephole through your door to see no one there, instead a cardboard box sits on your porch. You open the door, bringing the box inside before placing it on the kitchen table. As the box sits on the table in front of you, you can’t help but wonder what on earth it could be. Checking the shipping label on the box, it is addressed to you: even though you didn’t order anything in mail. Retrieving a knife in the kitchen, you go to open up the box to see what is inside.

The Knife slices through tape and cardboard alike, unsealing it, only to reveal a large stone tablet that looks incredibly ancient. Before you can do anything else, a green glowing aura emits from the tablet before surging towards you; the glowing green aura surrounding you entirely. Then the green glow seems to sink into your body before abruptly disappearing. Immediately your skin begins to itch as smooth scales appear across your entire body. An intense heat emanates at your core, your very DNA restructuring itself.

What do you do? Do you panic? Do you fall to your knees from the sheer intensity of it all? the choice is your’s
