Skuthosiin

Skuthosiin "the Venomous" was a fiendish green dragon and one of Tiamat's chosen.

History
Skuthosiin was born to the dragon Chathuulandroth. He was invested with a third of Tiamat's divine power during the Time of Troubles but was devoured, along with Gestaniius, by the bearer of another third, Tchazzar.

During the Dracorage, he was resurrected by Tiamat and sent to the Methwood to create an army for Tchazzar, who was now his ally.

In 1479 DR, Skuthosiin organized the ash giants of the Black Ash Plain into an army to invade Tymanther. The army was driven back into the plain and Skuthosiin was killed by dragonborn led by the paladin Medrash.
