Tomb of Rassilon (The Chronicles of Doctor Who?)

In Barusa's universe, the Tomb of Rassilon was a hidden crypt carved into the cliffside of a mountain on Gallifrey. With great effort, the Doctor discovered the mountain's caves and climbed deep in their heart, finding the Tomb at the centre of the mountain. There, in a pot, he found the Lost Scrolls of Rassilon. (PROSE: The Chronicles of Doctor Who?)

The Infinity Doctor remembered trekking through the mountains and finding something important in an ancient cave while sheltering from a storm. (PROSE: The Infinity Doctors)
