Do'enthan-greo

The Do'ehnthan-greo (often shorted to 'the Greo' in the later ages) are a set of interdimensional pathways created during the Age of Erudition. They were created by Oyvind Naero, one of the scholars at the conjuration university in Kisebinsk with the intention of making travelling between the seven academies faster and easier; one day of journeying in Do'ehnthan-greo is equivalent to seven days of travel in physical world.

A gate was built at each university, each made out of stone and enchanted so that they would never degrade or collapse; only arcane means could destroy them for good. Stepping through the gate leads to a small stone cavern that in turn leads out into the Ways of Do'enthan-greo, a collection of floating paths that don't seem to follow the laws of physics; the roads can seemingly fold over each other or slowly spiral under itself.

Such form of travel was lost after the Hundred Year Blackness, and Do'enthan-greo fell dark. Few have attempted to travel it since then - opening the gates requires arcane strength that few have (and those who have it often know better than to enter the Greo).
