Iydrioth Mountian

A mountain in Nroh's northern lands, it is the tallest in Syrunn.
Perpetually covered in snow and ice, it is deathly cold at its peak, not to mention the air is much to thin to survive without some other means. There are also monstrous creatures living on the mountainside. Its summit is next to impossible to reach for any normal being.
Yet... At its peak there is a frozen over shrine, with symbols on the walls and alter that is unreadable, even through magic.
Legends say that it was once used by the Six before the Drow came to inhabit the area.
