A Teleport Scroll utilizes the power stored in a Hereafter Stone to open a Worldgate. Jump through the gate to travel to a recordered location.
Hereafter Stones contain enough power to send you anywhere on your current continent. Refined Hereafter Stones contain enough power to send you to a different continent.
Note, not to be confused with Bound Hereafter Stone and Refined Hereafter Stone, the former of which is a quest reward and the latter which you can acquire from [[ArcheAge: Mirage Isle|Mirage Isle to teleport cross-continent.
