Maria is a recurring Pegacorn hero who first appeard, roughly seven years of age, in the story "Innocents".
Maria would ultimately grow to become a powerful sorceress and a high-priestess, she was also the one entrusted by Red and Inferno to spend most time with Sangria during times of war and she was known to be surprised when Red gave Sangria to Equis rather than herself following the events of Paint It Red.

(more background info will be added later on - the pegacorn concept is (to my knowledge) Inferno's work - Maria is simply a character I have created for part of the story (which is said to be a prequel) )
