Imagining a myst gatcha where you pull a series of increasingly unhinged older men who are angry at Atrus, just plumbing the hypothetical depths of his family tree and people who knew them. Catherine just going "I. I don't know who that is" to more and more of them. There are three Yeeshas you can pull. Everyone is grainy fmv or weird 3d models. We get summer skins but it's sirus and achenar looking like they washed up after shipwrecks. Saveedro finds better curtains to wear. The bahro are there and nobody is sure what to make of it.
Two years in there's an Uru expansion full of people from the DRC and nobody knows who the fuck they are. Several puzzles hinge on an advanced understanding of the d'ni timekeeping and calendrical systems for some reason.
