Thilas Baccan was one of Addryn Thane's most successful henchmen. In 989TA he successfully deposed the ruling Velwyth family of Deep Hollow and began a reign of oppression that was to last for eight years. His government was itself overthrown by the rebellion of 997TA.

He is a superlative mage with a great repertoire and many powerful items. He also has the uncanny knack of escaping from the most difficult situations unscathed.
