Alduin's Wall Charts the Entire Series
The massive stone carving known as Alduin's Wall, which kicks off the hunt for the Dragonrend shout, hides visual references to events from earlier Elder Scrolls games: the Staff of Chaos from Arena, Numidium from Daggerfall, Red Mountain from Morrowind, and an Oblivion Gate from Oblivion, all worked into the carved history of the World-Eater.
