The main reasons I'm interested in a Nightrider are that (1) it fits a nocturnal theme, (2) it resembles a regular Chess piece enough that someone could recognize it as a Chess variant piece if they saw it out of context, and (3) it is one of the better known fairy chess pieces. Some other pieces of yours that might work for the first two reasons are Midnighter, Moonrider, Thaumaturge, and Luna Pawn. So I would be interested in seeing these with a neutral background too.
