I reccomend Alabaster: The Doomed Session (and as a bonus to that, the cerulean motley crew, due their crossover) It’s really good, and has some base homestuck as background characters.
It’s a fantastic piece that dabbles in horror through pushing the scarier aspects of sburb and troll culture to it’s limits.

A real nice piece about the folly of trolls.
It’s still ongoing and even updated recently!
It’s one of my favorite pieces at the moment!
