From the initial save point, move forward. It’s really hard to miss this one.
After defeating Zaveid, go forward to see an uncrossable giant chasm. Move south a little bit and you will find it.
After finding Discovery Point (Rayfalke Shrine), go to higher part of the mountain. You will find it on the way to the 2nd save point on this area.
You need Edna (earth ability to destroy rocks) to get this Normin.
==Grave Atop the Mountain==
Check the grave on the summit where you fight Eizen.
