The Shrine belongs to the palces where creating a portal is difficult and highly unreliable. Even if you succeed with the portal and even if you check it by teleporting to it, even then you can find out later that the portal has evaporated somehow.

I don't know why this happens. You can create a portal there and teleport to it so that portals and teleporting aren't forbidden in the Shrine. When you cast Create Portal, you always get the "Portal created" message. Don't be mistaken, shit has been created in most cases, not a portal! In the rest of cases, the teleport does exist and is functional - now. Don't make any conclusions from it. Grrrrrrrr!
