Roan

Any clothing style in his colors are ok (black, silver, blues, teals), he's a fae time traveller!

Roan is a thoughtful and often serious fae, his appearance and coloration is based on the blue roan horse, and he is often in his feral form.  He has a token that allows him to travel back and forth from the human to the fae world, and he appears to help horses in the mortal world navigate distressing situations they would otherwise not understand.

He's a sort of sage/mediator, and might help a human's horse become more well-adjusted, or might arrange the untimely death of a human who has neglected or put their horses in harm's way.

He was part of a fae court where he was bound in service to a fae lord, but was stolen away and bound by a human, Eochaidh, who now travels with him, pursued by said fae lord, who wants his time-traveling steed back.
