@Finrod Pu is psychic university. They used to be a vendor but since a lot of the vendors on the forum started using dreams forum as a way to promote their own stuff without giving anything back to dream (some might call it parasitic in the literal sense as in profiting off of someone without giving something back like it would be in an symbiotic partnership)
They still have gumroad and patreon, you can find them there
The vital energy stack is mostly made of dreams’s creations but Tejas alchemy is an nft which can only be bought through the official nft sell and trade thread since the sapien shop closed down back in july
