Kortha’s Pyramid, Forgotten Chambers (The ‘Kortha’s Pyramid cells would be like this, at the Kortha’s Pyramid cell, the first one, there would only be the entrance to the pyramid, nothing else; and to open the door to the pyramid, you’d need to solve a puzzle of the sorts. Descending the list, you’d travel down the different cells until you hit Kortha’s Lair, where you’d fight Kortha, a dead Redoran House Leader Dunmer. After an intense battle, you kill him and get his sword and a secret door is revealed that bring you to the Rotted Catacombs (think the sewers of Mournhold) and through a small maze of catacombs, you get to the Forgotten Chambers, which lead you to the next level, out of the pyramid.)
