The Watermice are a group of thieves first encountered on the Doodler’s quest to save Nick Close. They are located in the forests around Waterdeep. Typically, when people join, they are indentured for a while before eventually deciding that they like the work. At that point, the spell that makes people lose their heads if they don’t complete certain jobs wears off.

Ellory heads up one of the smaller chapters.

Save Nick Close

After being sold into slavery by the Lance, Nick Close found himself in servitude to the head of the Watermice.
