The Enchanter's Rats
Ask around for the latest rumors in Vivec 's Telvanni Canton and you'll hear about a rat problem that Audenian Valius has been having on the Waistworks level in his enchanter shop. Talk to Audenian Valius and you'll find that he wants you to kill some rats (which are actually Telvanni sewer rats) and that he's got two holed up in his bedroom.

Even more Rats
After dispatching the two rats in his shop, he claims that he wanted ALL of the rats killed and points out that he believes they are crawling up from the Underworks (sewers) of the Canton. Investigate the Telvanni Underworks to find 10 more rats that need to be killed. The rats should not appear before the quest is active, and you should receive a journal update when you kill the last one. Some of the rats may be in the water, even possibly swimming along the bottom and never coming up to attack you. Return to Audenian for a reward of a Grand Soul Gem.
