Anthilar

Anthilar was a lich of history in Tashalar.

History
Antilar was one of the main leader of Untisczer in 285 DR but managed to survive his city's destruction at the hand of the Shoon Imperium relocating in a secret lair in the mountains west of the Tashan Gap. There he became a lich with the goal to control the merchants of Tashluta.

In 1056 DR Antilar resurfaced and unveiled the reigning oligarch as a yuan-ti abomination; this started a spell battle between the two than ended with the yuan-ti dead and the lich severely incapacitated. Protiiting of this occasion Anthilar's body was encased inside a massively armored metal "lich’s coffin" and shipped north by the priests of the  Skullspire  in  Tulmon to the Myrkulyte Conclave of Doom for study. However during the travel the coffin was steal many times. At last it entered in the hoard of Tostyn Alaerthmaugh, a young adult male mercury dragon lairing in the depths of Everlake, in the heart of the Evermoors.
