Senker Later was the Demoness of Sloth, one of four demons who resided in Quaint. She lived in the garbage-strewn alley behind the city's former Palace of Earthly Delights and was much diminished now that the populace had fallen under the sway of the virtuous health-based regime of King Macrotus and the Lady of Beneficence.
Senker was a tiny woman who appeared "as if some perverted inventor had fashioned a breastly, slim-legged doll upon which to lavish sick fantasies."
The tiny Demon of Sloth lazily sprawled in her alley next to Nauseo Sloven, Demon of Corpulence. Unlike the others, she seemed content to remain immobile. When the chaos inspired by Bauchelain, Korbal Broach, and Emancipor Reese energized Nauseo Sloven, he puffed up with greed until he filled nearly the entire alley, nearly crushing Sloth under his bulk.
