Thaxll'ssillyia

Thaxll'ssillyia was a shadow dragon brought with him from the Plane of Shadow by the Shade Lord during his attempt to extend his influence onto the Material Plane. Thaxll'ssillyia was left to guard the entrance into the Shade Lord's inner lair in the old temple to Amaunator near the Umar Hills. In the game the player character must pass the dragon in order to complete the quest at Umar Hills, but may instead of fighting use a wardstone that makes their party undetectable by it. If killed, Thaxll'ssillyia leaves behind hide that can be made into a powerful set of light armour.
