Princess Apple Tart
nicknames; appie, trouble
age: 17
special talent: baking, specifically apple-based foods
orientation; bi
info: no one really knows where apple tart got her wings, but she definitely utilizes them. she’s a bit of a troublemaker and likes adorning the castle in harmless traps and pranks. she’s nearly identical to her grandmother, Pear Butter, which great granny smith reminds her of often (no one knows how she’s still alive and kicking, but they dont complain)

Prince Comet Trail
nicknames: comet
age: 16
special talent: star tracking, astronomy (his cm is a comet)
orientation; demiromantic ace
info: a huge dork, but very sweet, spends a lot of time in the top floors of the castle gazing at the stars. he ended up making friends with princess luna and he’ll spend time at the canterlot castle with her at night, and it seems as though he can predict comet passings, which may be a hint of magic he inherited from his mother. his mane is un-tameable
