D&D 5E With Fizban's and now Bigby's, what other groups do you think we'll see with their own books?

[Older Beholder]

Unlikely, but a Creatures of the Underdark could be interesting, although I'm not sure there's that much left that hasn't already been covered in detail.

My bet would be for a Liliana's Libris Mortis, yes, even if Liliana is a planewalker from M:tG, but today the limits between D&D and M:tG are more and more diffused. Fistandantilus from Dragonlance was a relatively famous necromancer, but now "he is not in this neighbour". Gilidarius, Raistlin's former apprentice is practically unknown. Or maybe a Ez d'Avenir's guide of undead.

The next one should be a new edition of "Lords of Madness" about abominations.

Given that they're bringing back Planescape, perhaps something along the lines of "Skall's Book of the Dead"?

edit: I can't say I'm particularly up on M:tG lore, but isn't she mainly an antagonist? The monster books have been named after (arguably *) friendly NPCs, and the players option ones after antagonists.

Vecna's Scriptorium of Shadows?

Vecna's Scriptorium of Shadows?

Vecna's Crypt of the Dead

I filtered the necromancy spells and the only one that had a proper name associated with it was Abi-Dalzim’s horrid wilting, so that could be a possibility, but I think Vecna is a more likely choice.

 

[Daemini]

Tasslehoffs Tangible Tales of Twisted Terror

 

[Veltharis ap Rylix]

Somebody (I can't think of, sorry) Guide to the Abyss

I imagine that would inevitably be "Iggwilv's Demonomicon".

Excellent point on elementals. There's plenty of room for bestiary additions (genie and elemental variants, para-elementals as you said, maybe even the quasi-elementals and energons), and lots of possible player options/info (genasi info, elemental subclasses as you said, and potential warlock patrons). Lots of possibilities for magic items and spells as well. And it could even double as a sourcebook for the Inner Planes, assuming that Planescape more or less ignores them as it has in the past.

You could bring back Primodials in a big way with an elementao book too.
