South Road

Main quest:
This one is the easiest main quest ever! Go to Charwood village and then into an inn and talk to a man there to reveal him as a cultist! Kill him and get the evidence. That’s it! You DON’T HAVE to do anything else here unless you want to.

Other quests:
Castle Jhareg: in the village of Charwood, go to the Mayor’s House and speak to the local mayor to reveal details about the town and the castle. And you get a quest. Go to castle Jhareg and search the chest for a key. The key unlocks one of the three doors. The side doors will get you into fights with elementals while the middle door will get you a reward with no battles. Speak with the guardian (elemental) in the hall and it will tell you what you need to do. From now on, you will be the Judge. You have to find out who is guilty, Karlat or Quint. It doesn’t matter which room you will visit first, but I’ll start with Karlat’s chambers.
You need to find some items here: Karlat’s key (northwest), Karlat’s burning wand (northwest), Karlat’s wand of protection (east) and Karlat’s journal (east). Save the wands for later. You may also want/need to read the Summoning Tome and have some Fire Beetle bellies (one actually).
After reading the tome, go to the summoning chamber (with braziers in it) and place the Fire Beetle’s belly in the brazier, cast protection from evil on yourself (protection wand) and then cast burning hands (burning wand) on the same brazier you put the belly in. A demon named Belial will appear and you will be able to choose: you can either ask him for a magical item (bad) or get his oath (good). To the south, there is Karlat’s room. Speak with him and retrieve his oath.

Quint’s chambers: to the north in a small room there’s Quint’s key to the southeast is Quint’s journal and to the south is Quint himself. Speak with him and retrieve his oath.

Now all you have to do is return to the guardian and tell it that you have the oaths and you can summon Belial to uncover that none of the brothers are guilty. And you can take the phylactery and end the curse forever or leave it. Better take it.

South Road northwest cave: there’s a dead body with a journal on it and also there is a well in the cave. You can dive in if you have enough Constitution (you can try raising it with Endurance potions). On the other side there’s a skeleton (pull the chain) that will ask you a question and you can answer it if you have the journal. There are some nice items there.

South Road Farmlands: You can talk to the people there (I think northeast maybe, easy to find) to get a quest to get rid of the wolves that have been attacking the farms, cows, whatever. Just go to the nearby cave and kill the wolves mainly the Silverback wolf. You can leave the wolf alive and persuade it not to attack the cattle but then you will have to persuade the person that gave you the quest too.

South Road Erik’s despair: this quest can be found in Erik and Ingo’s home, marked on the map. Erik wants a brooch back. You can either go to O’Deel’s ranch, and buy the brooch from Constance or kill her or whatever you might think of and return in to Erik.
