This here is Wax n' Wane, a bat pony.
His special talent is candle-making, and his hobbies include spelunking and treasure hunting. The one unique feature he possesses a pair of curious marks on his forelegs, which light up in accordance to the position of the moon. To put it simply, his forelegs glow brightly on a full moon, but are otherwise dark on a new moon.
He otherwise comes from Hollow Shades, the ancestral homeland of the bat ponies. In short, he was born of a noble family but renounced his lineage and bloodline after a series of major disagreements with his family.
Presently, he hangs his hat at the inn of a griffon named Stuart Thatch, a modest establishment on the outskirts of Trottingham proper.
Personality wise, he can be... fickle. Some days, he can be as pleasant as a gentle breeze on a warm summer night. Others, he can have all the combined cheer of an entire graveyard. M̶r̶.̶ ̶T̶h̶a̶t̶c̶h̶ ̶a̶d̶d̶e̶d̶ ̶t̶h̶a̶t̶ ̶s̶u̶c̶h̶ ̶a̶ ̶s̶w̶i̶n̶g̶ ̶m̶i̶g̶h̶t̶ ̶b̶e̶ ̶h̶i̶s̶ ̶c̶o̶n̶n̶e̶c̶t̶i̶o̶n̶ ̶t̶o̶ ̶t̶h̶e̶ ̶m̶o̶o̶n̶ Mr. Thatch has no real bearing on what manners are. Period. Generally, Wax will do what he can manage to help, but otherwise can be put off by what he calls a "roaring sense of inadequacy".
His goals are to figure out more about his connection between the glyphs on his forelegs and the moon, as well as any other implications to be drawn from them.
