Obscura

Obscura is the counterpart to Aura, and the fuel for Ghost and Dark type moves. Aside from attacks, Obscura mainly deals in illusion. While most illusions are merely parlor tricks, sufficient skilled Obscuric sensitives can create permanent illusions (Such as Fool creating Minty and Butterscotch), and Annoski's illusionary wards, which were capable of placing the whole of Sinnoh under Twilight.
