Just wondering in-case I want to make a crazy character who is more cheerful than the grim Groetus. I guess Calistria would kind of work (she seems kind of psycho even if she doesn't have Madness in her portfolio), but is there anyone better?
Tsukiyo? The tian moon god.
Aside from Tsukiyo, we have...
Sivanah, mistress if illusions
The Lantern King, the loveable scamp
The Lost Prince, a sad boi
and of course Azathoth, who is just vibin'
I'm sure there are others, but what more do you need?
If all you're after is hallucinations then the absolutely Good Chucaro has you totally covered.
