The Great Fracture
Refers to an event 100 years ago, when The Five faced off against the ancient leaders of the dragons, the Elder Council. By a great sacrifice of two of The Five’s members they were able to destroy the dragons. This unfortunately had the after effect of shattering the continent, searing large portions of the land with arcane energy, and even changing the Mageplane into a twisted version of itself. This has shaped The World known today.
