Mistform Cards are three by five inch cards that allow who ever uses them to summon people and objects to their aid when needed. When done with the mistform, one simply taps the card and the image returns.
Alabaster C. Torrington uses mistform cards to summon his fake father and his sword. After his mother separates him and Lamia, they are all burned up. Howard Claymore later comes to him as a mistform.
