Frozen Valley
In Tales of Arise, the Frozen Valley lies outside of Cysloden, and you have to pass through it first in order to reach the next realm in your adventure, Elde Menancia. This is a short area and is fairly linear, but there are a few treasures along the way and a Dahnan Owl. This area has the same enemies you encountered in the Nevira Snowplains.
The drawbridge you see can't be crossed yet, so you'll have to go around it. The ladder to the left of the drawbridge has Rosemary. Climb back up the ladder and continue along the main path to find a second ladder to the right that leads down to a red treasure chest containing a Zeugle Shell Mage Coat for Rinwell.
Go back and continue along the main pathway to run into Gourdeno, a very odd man that will teach you the Apple Pie recipe. If you're familiar with the Wonder Chef in the Tales series, you'll be reminded of him. For more recipes you can discover in this game, check out IGN's Recipes section of this Walkthrough!
There's also a white Dahnan Owl in the tree to your left before the bridge and a man to heal at the base of the tree with the Dahnan Owl. Continue across the bridge to find a merchant and a campfire. Replenish your supplies and rest then move on to the Safar Sea Cave. The Safar Sea Cave is the last area before you reach Elde Menancia.
