How to Summon a Monster: Chapter 1: Burgles

Origin:

• Emergence from flawed summoning rituals, particularly by inexperienced summoners.
• No precise knowledge of their original realm or dimension, although endless spawning is theorized.

Appearance:

• Initial appearance features large (8-12-feet to the shoulder), long bodies, black feathers, mottled grey skin, and bone-white, stiff masks.
• Tails are long, tapering, whip-like, and prehensile.
• With age, feathers change color to blend with the environment, usually within 1-2 months, and masks darken. Males grow larger while females shrink slightly.

Abilities:

• Capable of swallowing creatures their size or smaller rapidly due to greatly expandable stomachs.
• Immunity to physical damage but susceptible to elemental and magical damage.
• Digestion of living matter takes around one to two weeks.

Behavior:

• Initially chaotic, relentlessly seeking to consume or pleasure themselves with living creatures.
• As they age, they lose chaotic tendencies, becoming more adept at securing prey and staying hidden, indicating maturation.
• Once tamed, they exhibit intense loyalty and protectiveness towards their masters.

Taming:

• Taming more feasible hours after post-emergence, especially before hunger satiation.
• Exceptionally skilled summoners might halt the summoning process and bond with a Burgle, preventing a rampage.

Society and Worship:

• Solitary beings with no observed natural reproduction, yet possess reproductive organs.
• A small sect of cultists revere and worship them.
• Notable individual: Boomi, a centuries-old female Burgle, tamed by Omni, smaller in size, tawny-feathered with a dark chocolate mask.

Aging and Maturation:

• Over time, Burgles mature, becoming more effective at hunting and staying concealed.
• Physical changes include coloration of feathers for camouflage and darkening of masks. Size differentiation occurs between males and females.

Inspiration and Analogues:

• Inspired by Skullcrawlers from Kong: Skull Island but with feathered, four-legged variations.
• Envisioned as Avian-Mustelid skull creature monstrosities.
