So, recently I finished up my plot for ModTown 2015, but one thing that's preventing me from finalizing it is the fact that I don't know how to prevent teleportation magic to work in a single cell. The idea is to only be able to use a scripted item to teleport out of the cell, which I already made and it works. The problem is that the quest can pretty much break if you teleport out of the cell by using teleportation magic like recall or intervention. Is there a certain script to block those spells in this particular cell? I know something similar is used for Mournhold, but only works with levitation. Any ideas?

You'll use the "DisableTeleporting" function. Take a look at the script I have in "DIppy Dorugg's Deep Dive".

Thanks. I got the script working. Now, I just have to replace the rest of the placeholder meshes with new models and the plot is done.

Edit: Word of advice: Melian's Teleport mod is highly incompatible.
