Arzkiya originally wanted to be Arzhai. However, as a certain prat had already called dibs, Arzkiya is, well, Arzkiya. That apart, Arzkiya previously went by the name of The Quaint Quenyan. In the real world, people usually call him by his name or, to be a tad more precise, a part thereof, when in a nice mood. Otherwise, they call him other things.
