Mortlock Vanthampur
From For Companion and Country
The youngest son of Thalamra Vanthampur. Headed up the operation in the Dungeon of the Dead Three until his brothers, who both dislike him, decided to have him assassinated by Vaaz, the Death's Head of Bhaal who was also in the dungeon. While the party saved Mortlock and pumped him for information, they ended up taking him into custody.
Mortlock's face was scarred by fire as a child, but the disfigurement mostly just makes him appear even more fearsome.
