Aha thank you! But I can't take the credit, Aretina created them and developed their traits, I just made a couple.
In general, however, Eisoptris, or Mirror demons, are complex creatures who take their home in the Crystal Continumm (from Frank Beddor's The Looking Glass Wars), a network of transportation in Wonderland. Mirror Demons usually appear as smoke, and take over a host, or are descended through bloodline. Hosts and others and able to step into mirrors and appear somewhere else.
