Horrors in the Highland

These brackish wetlands hold a greater well of unsalted southern waters. It pains me, yet within my roots I sense a corruption seeping through that mountain gully.

The creatures, like those in our lowlands, react more bitterly to the taint. Lacking the sea's hardening salt since life's dawn, they have little strength against such evil.

Go to those highlands, and bring me the Highland Horror's root core.
