Beware of environmental effect in the swamp that will poison players with AoE. The poison can be discerned as green-yellow smoke.
Saidra's Ashes can be found north in the swamp area. While holding it, you are under the effects of Courageous Was Saidra. It automatically drops from your hand after 300 seconds.
Near Saidra's Ashes, there is an island chain on the coast with a face in the stone of the waterfall; the eyes of the statue will follow your movement.
North of the Bloodstone Caves, around the beginning of the forest, in the raining part, on the wall to the right there is a big face carved in stone. The face's eyes follow your camera wherever it goes.
The NPCs Giriff and Tekks are references to the Red Vs Blue characters, Grif and Tex. The quests they offer concern two teams, Red and Yellow.
