Eidelmann's Stargate

You create a tear in the realities of two worlds and are able to merge certain aspects of these realities.

When you cast this spell, you can speak the name of a specific creature (a pseudonym, title, or nickname doesn't work). If that creature is in the reality you are targeting, 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 is free to act as the GM deems appropriate. It might leave, attack you, or help you.

Additionally you may warp your reality itself by merging together the aspects of the reality you are targeting and your own. This could have the effect of aging a specific person, increasing or decreasing specific attributes of yours or someone else's, or some other effect that you may come up with that your DM agrees to.

To Cast this spell the caster must be at least level 20, to help they must be able to cast 5th level spells.
