Thaxll'ssillyia

Thaxll'ssillyia was a shadow dragon brought 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.

Gorion's Ward and party had to pass the dragon in order to complete their quest in the Umar Hills, but could, instead of fighting, use a wardstone that made their party undetectable to the dragon. If killed, Thaxll'ssillyia's hide could be made into a powerful set of light armor.
