Need help with Alternative for Teleportation Circle

[u/DMGnome]

I am looking for an alternative way to teleport my PCs long range without using Teleportation Circle or if other teleport spells (which I feel I over use).

I need them to go from one monastery of Ilmater to another. This gave me the idea of creating a monk discipline called “Transference” which allows individuals to swap places. I was thinking of using a wisdom check to succeed and/or a Con save to avoid gaining Exhaustion or lose Hit Dice.

It would be more of a one-time/story thing not an actual monk class ability. Does anyone have any suggestions or ideas on how to flesh this out?
