What Dimension/Universe did the Titans run from
If I recall correctly, the Titans escaped from one dimension into the realm of Arborea and made everything in the empty dimension/universe in their sleep.
If creatures as powerful as the titans ran away from a warring dimension/universe, what was it like? Why hasn't anything of the same power as the titans come through to follow them. Surely if there where things as powerful as them, the wards around the planet/sleeping titans could be bypassed or shattered.
I'd like to see more about the titan's past and possibly a new zone/expansion in the old universe they ran from.
If anyone has more information on this please do share.
