I’ve long been considering running a solo game with 3 or 4 protagonists run by me, and using the storyline from Rise of the Runelords per PACG (I don’t have actual Pathfinder Adventure books on it) as a means for bringing some of my heroes to the same plane, though they come from disparate origins. This would tie into my EverMyst campaign, whose sole PC so far is a disillusioned elder Growth Walker of a nomadic desert-faring tribe whose identity is shattered when he comes to realize he doesn’t truly know all there is to know of his world, in discovering a Linking Book in a well-guarded library keep in the one immense city his world supports, whose origins date back to a handful of D’ni trying to escape the purge wrought by Veovis and A’gaeris. Needless to say they kept enough materials to author new Books. However, one or all the central characters also discover they possess spherewalking abilities when they accidentally pass through a gate, which may be seen as a parallel to the Book linking.

Veovis and A’gaeris, whose actions led to the destruction of the millennia-and-Age/world-spanning D’ni empire overnight, and whose supposed only survivors (Anna, a human archaeologist, and her half-D’ni son Ghen) fled D’ni in search of peace above ground in the hard desert life she’d already known with her fellow archaeologist father before he passed. Ghen grew up resenting Anna, returned to D’ni and eventually brought his son, Atrus, to help him study the Art of writing and authoring new worlds. Atrus turned against him when he realized his machinations we less than benevolent, after falling in love with Catherine, a denizen of one of Ghen’s ages with imaginative Age writing skills herself. All of these characters show up in fiction and in the various Myst-series games.
