Bipomop (Bye-pu-mop) is the village the Sin's Apartment is placed, and where the sins live. It's an ??? themed village, however, the virtues weren't born in this village, they were all born on different villages of different themes.
The sins, however, were born in this village, as they were born in Sacrificer's swamp.
(Keep in mind that the themes of villages in Dwurm doesn't always have to be country themes based on what we have here on earth, some themes could be items, beings, styles or anything really.)
