Írensaga
Irensaga was a mountain in the White Mountains, notable for its saw-toothed crest. In between Irensaga, Starkhorn and Dwimorberg there was Harrowdale.
[edit] Etymology
It means "iron-saw" in Old English, with reference to its serrated ridge, crest.[1]
In earlier versions of the legendarium Írensaga lacked an accent.[source?]
