The Moaning Lands of the Dead and Dying. Many foul creatures of undeath roam here and seek living flesh, no one is quite sure what happened to this large desert island. Maybe you could unlock the mystery and free the tormented.
What if casting magic changed (for a few hours or days depending on the strength of the spell) the colour of the skin of the spellcaster? It could lead sadly to a very racist world to rp in.
