Forgotten Vale Forest
The paragon portal teleports you to a small forested valley far north of the main areas of the vale. The broken stone arch forming the portal allows you to return directly to the paragon platform. There doesn't seem to be a proper path through the trees, and due to the density of the snow and trees it can be difficult to see any frost trolls as you approach; the Detect Life spell or the Aura Whisper dragon shout may therefore be useful. There are up to six frost trolls in the area. Eventually you will encounter a Falmer Warmonger, either battling some of the trolls or having defeated them, wandering near an unlocked stone chest. The Falmer carries the unique Auriel's Shield, and will attack as soon you are spotted. The chest is on a rise near the southwest wall by the remains of another arch, with a lootable skeleton lying on the ground in front. North of the chest is an overhanging section of the valley wall, where you may find one or two frost trolls. The only other items of note in the forest are three snowberry bushes and some broken masonry.
