The Veiled Tower
As the Ancient texts read, “Part the veil of the universe for me!”, the veil itself has to be somewhere. That somewhere is a tower north of Amnestra, deep within the eye of a sandstorm.
The portal system setup even before the rise of Amnestra uses this location as a link, entwining the paths between faraway lands. The tower itself only activates almost at random, activating long-dead portals that still exist.
The labyrinth within the tower draws those within deeper into a tear in the fabric of reality, a place between places. Those who enter are not known to return, although a minor mage of the Penumbra known as Lucas Pegasi, who has been said to be studying them, claims he’s seen the inside and returned.
