Vortex: A vortex (also known as "portal") is a pathway connecting two regions, sometimes over long distances. They have been created by the Karavan and/or the Kamis^{[missing reference]}.

Any homin can use a vortex. Animals seem very reluctant to go through them, but the pets follow their masters.
The most recent vortex has been linking the Dunes of Exile to the Knot of Dementia since 2527.
