Create Teleportation Circle is a 15th-level ritual.[MotP:149] You create a teleportation circle with a unique sequence of magic sigils, which you and other ritual casters can useas a location marker for rituals such as Linked Portal and Planar Portal. The teleportation circle does not transport creatures anywhere on its own—it merely enables other travel rituals. The ritual caster chooses the size of the teleportation circle, which in turn affects the ritual’s component cost: 1 square, 4 squares (a 2-square-by-2-square area), 9 squares (a 3-square-by-3-square area), or 16 squares (a 4-square-by-4-square area).
