Is This the Helkrax?

The preqel ri is set in the first age of tolgein's world. The show will focus on a woman named goladrie, who has been missing since her brother was killed by an ice-climber. She may be looking for remnants of morgoth's empire as she tries to track down his killers. But there are at least two other people with her climbing this frozen water - and they're not alone.
