I think that texture could work very well
I also had an idea, which might make some sense.
My favourite teleport mod is "Teleportation Spells." You have to buy fairly expensive spells that will transport you to most of the main settlements on the island, and you expend 100 magicka points each time you cast. You also need to be good at Mysticism in order to use the teleport spells.
IMO this is very realistic.
Would it be possible for the PC to somehow embark on a quest whereby the reward would be a "Teleport Home Spell?" Maybe you do some sort of a favour for a mage, like a rescue mission perhaps?
Just a thought anyway, and it would get you away from having to use some kind of item instead.
