Yeah - this is a genuine situation as Moder's radius is indeed huge and the mountains do drain stamina. Do it in two stages.

You need to build a portal just outside that radius. Then run in naked fully rested, with your best foods and anti-frost potion. You're probably going to die as you have zero defense against drakes and wolves, but might get lucky. If that doesn't work or you run out of patience, I'm afraid you need to gear up to the minimum needed to handle wolves and drakes. That may mean troll armour, your starting bow and a flint or bronze axe.

- Eat your best foods. And a frost resist.
- Stop a lot to regain stamina and scan for wolves.
- Always move with high stamina, never letting it go below 40%.
- Wolves are dangerous. If you see or hear one, stop, engage at 100% stamina. Full stamina means you can handle being rushed by several and win.
- Drakes are a non-issue as you just side step and shoot them.
- Hide/sneak as needed.
- Avoid Moder and run behind obstacles, but "only" in the direction you came from, where you've already cleared all the wolves and drakes to avoid surprises. Because the way you'll normally die is if surprised by multiple enemies.

Good luck
