Danketsu

A Hereafteran land that houses Spirits, as well as their Trusteds.

There are legends about this world circulating among living spirits, namely that it is a bleak and empty world and one may only find happiness there if they coordinate their death with that of their trusted. These stories are only rooted in fact retroactively; the Seraphim tried to adjust the world to match by allowing a spirit's trusted to come with them, but it isn't nearly as bleak as they think. In fact, with so few spirits being born, and much fewer making it to the Hereafter in one piece, the Seraphim are known to answer individual requests for climate, housing conditions, and nearby resources.
