well i accidentaly clicked fast travel on my no-fast ravel play, and hated myself so i guess this mod prevents that.

It is mostly to remove the tempation to fast travel, for players that give in to the urge that few can resist.

If you do a no fast travel playthrough than this mod stops you from accidentally fast traveling

Just for the helluvit, dude. :) of course you can restrict yourself but disabling it puts fast travel out of the question baseline.

habit. i want to do a sort of nuzlock designed for a non-pokemon game, in this case skyrim but i cant remember not to do things like fast travel, especially considering the increasing number of rules.
death is permanent, no fast travel as to avoid any possible enemies, no dragon rend, no followers, and all potions have to be player created.
