General headcanons about the AU the series takes place in (technically, an offshoot of the FMP 'verse)
Headcanons for Classroom Battlefield, my other FMP fic (which is on a whole different website)
Cute headcanons. (Relationship-related)
They're supposed to be cute so they can stay.
Lemon level headcanon? :X
VERY Offsite because they're more hardcore than spicy headcanons.
Wow That's Depressing/Miserable-type headcanons
Just... absolutely offsite, absolutely not-kid friendly, etc.
