Also silly idea for future, dunno if you plan it or would do it. But some people might enjoy it. Dronification themes? There are already void cages looking quite similar to what it causes. Just no events, or stuff, angelic realm. though dunno if it deserves own sub realm for angelic or adventurer realm. Could be also some assignment in sealed realm. Though there it might be too diluting considering how that realm works. But again it is just silly thought :P
