...
I believe there is also a Rune Castle here...
Upper area and Tundra:
All south over the bridge, there is a tomb
...
- Algiz seems to be a heavy one, though he is super hard as he heals himself, to get to him
- Enter the Rune Castle, go s.sw.w and search ang det the moon, then e,ne,se,e and search and get the skull
- then w,nw,s, unhold all, and climb the stairs (no autoattack up the stairs)
- kill the guardians (they are quite hard and can take massive beating), then
- insert skull
- insert moon
- twist skull
- twist moon
- If you "enter" you will get to a room with north and out exits and Algiz
- I suspect suspect Hagalaz (Quest 101 - Having thine health declining?) is behind Algiz
