Fey Portal

4th-level Conjuration

Casting Time: 1 action
Range: 30 feet
Components: V, S
Duration: Concentration, up to ten minutes

This spell opens a portal up to 10 feet by 10 feet (caster's choice) between the material world and the Feywild. Travel is freely possible in both directions, meaning creatures and objects from the Feywild can easily come through and vice-versa. The spell can be used to open a portal from either side.
The geography of the Feywild is based on but not congruent with the material world. Portals opened a few feet apart in the material world can be miles or more apart in the Feywild and vice versa. If a traveler is familiar with the Feywild, it is possible to travel a short distance in the Feywild and return to the material world vast distances away.
