Name of OC storyline might be Drugstore (you know what a drugstore is) Dumpbin (a freestanding box full of loose goods for sale) acronymised to DSDB. Or maybe something that uses the acronym CHN, as C10H15N is the molecular makeup for methamphetamine.
OC storyline based off of the silk road marketplace. Some girl, a trans woman, singlehandedly runs the servers and moderates the site for these anonymous transactions to take place. Furry (obviously), she's a mid-thirties pre-trans girl who came out late, straight-laced sans an addiction to meth shes trying and failing to kick (hello breaking bad). Made the site as a way to make easier her substance abuse and to take steps to acquire DIYHRT, though it slowly but surely spiralled out of hand. She pacified herself while slowly allowing harder and harder things the more money she made off of their transactions, but before long the paranoia got the better of her and she abandoned it all. Got really weird about killing it though, like she couldn't seperate where she began and the marketplace ended. Ends up taking her own life by hanging herself with her ethernet cable.
