[@chukklehed] You don't need to claim Gaster to just use him as history (Mostly cuz hes still dead, unless somebody does want to play him and can reason how he is alive.) Approved, make sure he knows Tauriel since she stayed in the Ruins as well.

Ganley does know Toriel, but because he's the royal Archivist. He had already moved to New Home before Asriel was born.
