Other Solar

Solar cultist would be cool for like another boss (post-moon lord) like an upgrade from the normal cultists. That would be cool.

This is already an suggestion:
The White Cultists

I just wish they could add it to the game.

 

[The Storm]

The developers have said many times that they do not want a post-Moon lord boss.

 

[REKTIO]

Then maybe a really rare mob that spawns only when you deafeat moon lord? Or could be in the mods.

Details make a suggestion. They help us envision what you have in mind. If you could elaborate on this boss, it would take the suggestion's quality up tenfold.
