I made Portal.
For Skyrim.

A lot of people have wanted to know how to make a Mark/Recall Spell, and so I spent a little time playing and came up with this. If there's interest I'll write a tutorial on the CK forum tomorrow.

I've been looking for a Mark/Recall type mod, that only adds Mark/Recall and nothing else, and that has been updated for 1.6.89 and above. I'll have to download this later, during my next mod update run, and I also love Portal, so good job!
