Primordial hypogean giants of myth who raised up the land and shaped it according to the will of Karna.
One titan, Aygir, rebelled and was exiled from the land. According to myth, the rest have been sent below to dream of a new world.
The gems found deep underground known as "titan's hearts" are used as a conduit to Profundum. With this conduit, boundless and convenient magical energy can be harnessed from the sentient witchfires of that burning otherworld.
