244 Aihrde/Erde 2000. Troll Lord Games' After Winter's Dark fantasy setting. Originally statless, then d20, Castles & Crusades, and 5e. I often get tripped up on where the h in Aihrde goes. 

Castylpunk243 Brinkwood 2021. Describes its setting as a Crystalpunk world ruled by vampires. Forged in the Darkness rules set.
I stand corrected.Castylpunk
It looks like it is an unofficial fan creation.There's an RPG called Subgrubs and Snazzards that's set in Alternia, the world of the psionic trolls from Homestuck, but I don't know whether it's an official product or not
