Skyrim Sidelines- Karthspire Camp (Part 2)
This platform contains a tent with some food and a potion in it, and beside the tent is another stack of supplies. More stored food is available here, as well as some canis root, a bulb of garlic, and a random weapon lying atop a crate. You can also use the down-ramp here to get to the riverbank directly, which is how you can access the nearby iron ore vein- and more importantly, the path North up the hillside towards Red Eagle's Ascent. That in particular is significant to a questline, so make note of it while you're here.
Nearly due East is the next platform, where there may even still be a Forsworn if you raided the camp by charging in with steel swinging. On the table here is another apothecary satchel, and you can drum up some more food- including salmon from the fish rack. The tent holds a shield, a book that may be of use to read, and still more food supplies. Outside the tent is a tanning rack, which you could well need at this point, as you're mostly out in the middle of nowhere.
You may hear a ringing sound from here, and those who recognise it can rejoice- there is indeed one of the valuable Nirnroot on the ground below. It is closest to the bridge that leads to the actual stone ruins, which is often covered by yet another of the Forsworn, and you can either leap over a railing to get it and then climb the riverbank or descend the riverbank from the end of the wooden bridge to find the Nirnroot.
While the far end of the bridge is itself unprotected, a Forsworn archer waits on the stone stairs up onto the ruins, ready to lay you down as you come up. One of the more melee-oriented Forsworn guards the main platform of the ruins here. Those of you who are sneaking into the camp will need to be careful- give her time to call out, and you will have damaging spells dropped into you by the Forsworn working the forge on the next layer up of the ruins.
