Landfall

Landfall is the term used to describe the fall of Mundus. It happened in the future, when the Thalmor finally were able to ascend to godhood, having destroyed the Towers, eliminated Talos worship, and purged all human races from Tamriel. Landfall caused the remaining elven races to flee to Masser. Landfall is detailed on Michael Kirkbride's C0DA and the Loveletter From the Fifth Era.
