sorry if this is rude or something but could you please elaborate on how a lord of heart could create a temporary afterlife but a lord of doom couldn't? my Doom friend thinks Heart would only be able to move/transfer souls rather than create a space for them, and I think they both would be able to but can't quite put it into words for Heart.

I feel this is associating Doom with Dying and, as such, with the Afterlife, but I feel Doom encompasses more the act of Dying than Death itself if that makes sense? Like… Limits, Ends, the domain of Doom is linked to these borders, whereas Heart deals with the Soul itself. Doom may be Death, but if you want to talk about the Afterlife, you’re moving to what comes After it, and there may be a divide there.
