A Skyrim player in Finland has found through a bit of tinkering that the entire map of Tamriel has been laid-out by Bethesda in the game, with both Oblivion and Morrowind landmasses accessible when using the noclip command.
According to the player, when he ventured over to the south-eastern corner of Skyrim’s map, he found that the archway of Stendarr’s Beacon, the closest point to Morrowind, contains a path that is inaccessible to the player.
Curious as to what lies beyond the archway, he used noclip to access the path, and found that the trees and foliage continue on for a bit before eventually thinning out with scaled-down textures.
Further exploring, he found the Red Mountain in Morrowind’s VVardenfell region, Solstheim, and the mainland. He also came across Oblivion’s Cyrodiil and the Imperial Tower.
You read over a description of what he saw, and have a look at screenshots he took as well through his blog.
It is unclear why the Tamriel landmass is present unless it was already mapped out by Bethesda ages ago, or if it is included for eventual modding purposes. It’s doubtful the developers included it for eventual DLC, but we can’t be sure about that either. We’ll send a mail.
Meanwhile, a YouTube user has created an absolutely gorgeous time-lapse trailer for the game, using hours of gameplay footage. It’s posted below.
