Concept: “The sewer guild has fled leaving these spaces to goblins and other chitter creatures, but they have left behind treasure and small stash of one of their key tools, Sewer Salve.”
Content: “a beard and skin care product that mixes the scents of patchouli, amber, and vetiver for a sweet earth aroma vaguely reminiscent of a urinal cake.”
Writing: I won’t spoil it, but there’s a pretty good pun on the lid.
Art/design: The most metal of yellow sewer grates.
Usability: A spreadable (edible?) urinal cake. I’ll get back to you once I get my hands on it.
