At the time of Skyrim, the tallest mountain would be the Throat of the World, as Red Mountain lost much of its mass after its eruption during the Red Year.
Tamriel is a region in a multiplayer online game called Elder scrolls online. It was originally developed by ZeniMax Online studios and was then published by Bethesda Softworks. The game was released on April 4, 2014. It has many mountainous regions.
However, the tallest mountain is a volcano. It is known by the name Red mountain and is considered the highest mountain in the realm. Hence, the Skyrims throat of the world is not the highest mountain in Tamriel. Many people have played the game and explored its depths. They roam these mountainous regions on different quests to find the answer to the problems of the realm.
