Could it be the ash lands or the burial mounds

It's Solstheim not Morrowind.

If they did have a part then it would be the top left corner or along that area.

No I mean to be transferred to solthisa whatever like red mountains eruption causes ash land like Terrain in the island

Ashlands is already confirmed.

It will have snow too obviously.

I was hoping for them now just add deadric spear and bam
