There aren't really any rules for what questions you can ask, but I personally won't answer anything like:
-Where do you live?
-What is your real/full name?
-Where do you go to school?
Other than that I think I'm good?
Characters (I might have more that I've forgotten but these are the main ones):
Cas: Tiny gay bitchy baby. Like cuddles and cats
Nathaniel: Smol angel with crushed wings. Angry and aggressive as fuck. Enjoys eating bagels plain and raw
Lloyd: Nathaniel's older brother. Voice of reason, huge nerd, low-key hates everyone. Also canonically dead
Scipio: Chaotic Neutral and pretty funny. Italian BastardTM
