Are there any non-player characters that have mantled someone's position? Besides Tiber septim of course.

Wulfaarth,Zurin mantled Lorkhan along with Tiber.
Martin Septim some say mantled Alessia.

What?

That martin thing actually makes sense, he basically remade the pact with akatosh and became the new barrier-guardian of Mundus.

Start of the covenant and End of the covenant or something similar.


Well Cider beat me to it.

The Grey-Fox curse.
All half-mantled. They became the Grey-Fox while the Grey-Fox failed to become them.

Ysgramor being mixed up through different generations. The kings or chiefs of Nords became Ysgramor and Ysgramor became them.
