His name is Midnight Star Splash
He is a painter
His age is unknown
He is taller than Luna but smaller than Tia
He lives in the evergreen forest, deeper than the sisters old castle
He comes to Pony Vill from time to time but always keeps his wings covered, not want to deal with bowing
He's very kind and loves kids, wishing that he could play with them but again wishes to not deal with bowing
He is a crowned Prince, being the younger cousin to Tia and Older than Luna
He is 'Hiding' from his Royal duties, wishing to paint more than anything
Tia and Luna know this and are giving him time to himself but know where he lives
(Will come up with more later)
