Back in 2018, DarkFox127 (Moskom Estate, Caranthir Tower, his YouTube series on how to use the Creation Kit) put out Shalidor's Migrant Portals. It's a pretty nifty mod that, after a short quest (tied to a longer quest), gives you 5 platforms you can use to instantaneously (but immersively) teleport between anchored locations. Since I tend to build bases around Skyrim, this has a permanent place in my load order.
But, in 5 years, this mod has garnered all of 171 endorsements, and that's just wrong. DarkFox probably doesn't care that much about this mod, but I'm throwing this out there in the hopes that someone who might enjoy something like this finds it and, maybe, passes the find on to someone else. It's too useful to fall off the map like this.
