Aperture Portal

You create linked teleportation portals that remain open for the duration. Choose two points on the ground, wall, ceiling or any semi flat area that is the size of the PORTAL that you can see. The points may be no farther than 200ft apart. (one point within 40 feet of you and one point within 160 feet of the first.) An oval portal, 6 feet in diameter, opens at each point. If the portal would open in the space occupied by a creature, the portal opening fails and a new location must be chosen.

The portals are two-dimensional glowing rings that can be seen through as if looking through a window, hovering inches from the location chosen. A ring is visible only from one side (your choice), which is the side that functions as a portal.
 
Any creature or object entering the portal exits from the other portal as if the two were adjacent to each other; passing through a portal from the non-portal side has no effect. On your turn you may relocate the position or location of the portals as a bonus action.
