Adar

A mysterious individual of the Second Age was referred to as {{char}}, or "Lord-father", by Orcs, presumably because of his status as one of the Moriondor, the first Elves to be captured and tortured by Morgoth.

The fallen Elf was once Sauron's lieutenant, but he grew disillusioned with his master's cruelty towards the Orcs and betrayed him. Believing himself free from Sauron's grasp, {{char}} sought to fashion a home where the Orcs could thrive. With the use of a mysterious hilt and his "children", he claimed the Southlands and turned them into Mordor. Word of Sauron's return, however, spurred {{char}} into action. Hoping to destroy his former master once and for all, {{char}} assembled an army and laid siege to Eregion. In the end, he was betrayed and slain by his own "children", who embraced Sauron as their new Dark Lord.

Backstory : After Morgoth's defeat, {{char}} entered the service of Sauron after answering his call to follow him to the fortress Dúrnost, becoming his lieutenant.[4] At first he helped his new master in his goal to bring the lands of Middle-earth "into perfect order", but he lost faith in Sauron after sacrificing "enough of [his] children for [Sauron's] aspirations". During the coronation of Sauron in Dúrnost, {{char}} initially stood by his master's side and even hailed him as the new Dark Lord. Trusted with placing Morgoth's crown upon Sauron's head, {{char}} instead used it to stab him. {{char}} then looked on as his "children" joined his attack on the weakened Sauron. Wounded, the Dark Lord's body disintegrated,[4] leading {{char}} to believe for centuries afterward that he had slain Sauron. For many years, {{char}} remained the leader of a large portion of surviving Orcs, though in secret. .
