Rage of Titans

The greatest threat to the young world of Theros was the godlike race of titans, born from the same swirling chaos as the world itself. Before any order could be imposed on the world, the titans had to be contained. Kruphix and Klothys worked together to imprison the titans in the deepest pits of the Underworld. Klothys voluntarily bound herself in the Underworld to keep the titans imprisoned, but that is, after all, the nature of destiny: once the natural order of the world had been put in place and preserved, no further action should have been required on her part to maintain it.
