Vertan is used as both the term for the homeland of the Vertani and a term for the collective Vertani peoples. Vertan itself has never been accurately glimpsed through the portal from Sapience to Vertan. After the entire debacle, the remaining Vertani military forces were either destroyed or returned through the portal (after a siege that took several months), except for a number that went with a commander named Daqsool to seek asylum in Shallam.
There was once a report of an entry through the portal by an Achaean, but this was never rightly proven. Around the portal from which the Vertani entered, plant life was found dead and burned. Further examination of this portal was conveinently stopped by a fortress constructed around it.
