You make a portal in an unoccupied space you can see that goes to a precise location on a different plane of existence. The portal is a circular opening 5 to 20 feet in diameter. You can orient the portal in any direction you choose. The portal lasts for the duration.
The portal has a front and a back, but travel is only possible through the front. Anything that moves through it is instantly transported to the other plane, appearing in the nearest unoccupied space.
Planar rulers can prevent portals from opening in their presence or anywhere in their domains.
When you cast this spell, you can say the name of a specific creature and it will be pulled to the nearest unoccupied space next to you.
If that creature is on a plane other than the one you are on, the portal opens in the named creature's immediate vicinity and draws the creature through it to the nearest unoccupied space on your side of the portal. You gain no special power over the creature and it's free to act as desired.
