Arvena Thelas

Arvena Thelas is a Dark Elf living in the city of Anvil. She plays a role in the first Fighters Guild quest, A Rat Problem where she wants to know why some of the rats in her basement are dying. The Hero of Kvatch later finds out that the cause of the deaths was a starving Mountain Lion that had been attracted to her basement by pieces of meat left by Quill-Weave.

Trivia
Arvena Thelas has a sister in Morrowind named Drarayne Thelas. She too is part of the first Fighters Guild quest in The Elder Scrolls III: Morrowind, where she wants the Nerevarine to kill Rats in her house.
