House of Illthrix

From publisher blurb:

Illthrix was an evil genius that liked to kill adventurers. His dungeons and traps earned him a measure of infamy matched by few villains of the age. He's dead now. But, you've found a way to his hidden lair - Illthrix's own home. A place rumored to contain special trophies and treasures from the long career of the famed trapsmith. Illthrix wouldn't bother to trap his own house, would he?

This is the first of three connected adventures for the Avremier setting. It can be played by itself, or as the opening of a larger adventure.
