(Defeated the Hydra at the Encampment.)
An Uninvited Guest [Cassardis - 1]
Talk to the Cassardis Inn keeper. He will tell you about a thief and ask you to talk to the other shop owners. Once you’ve talked to them, report back to the Inn keeper. He will ask you if you’re ready to catch the thief. Confirm and it will become nightfall. He will tell you the thief will come and be ready. Simply wait for the thief to show and try to grab him by pressing

when close. You can choose to chase him, but you can also wait at the exit gate, because that’s where he will always go. You can also attack him which may cause him to stop for a brief moment. Use this to grab him.
Deep Trouble [Cassardis - 1]
Close to the exit gate in Cassardis, you can see a well on the right with a guard standing next to it. Talk to him to start the quest. Go inside and move all the way to the back and kill the saurions there. Once you’ve killed them all, you need to report back to the guard.
Deeper Trouble [Cassardis - 1]
After meeting the Duke, go back to Cassardis. As soon as you enter Cassardis, the camera will change towards the Well and you’ll hear a voice. Go down once more and talk to the guy below. Follow the quest marker. Kill all the saurions there and destroy the eggs. Be careful, a Saurion boss will spawn. (This quest can only be started after completing "Deep Trouble". If you can't start the quest, leave and enter Cassardis again.)
Guard Duty [Cassardis - 1]
At the Inn, you can find a woman in yellow called Madeleine. She can be either down- or upstairs. Talk to her to start the quest. You’ll need to escort her to the Encampment. Before starting the quest, you might want to rest till morning so that there’s a higher chance you don’t have to fight with any monsters. It’s only a short distance. Once you’re at the Encampment, she will ask you for 1.000 in gold. Give it to her. You don’t have to, but if you don’t, you’ll miss out on the
The Patron trophy.
Lost & Found [Cassardis - 1]
Go to Cassardis and find Chief Adaro (old guy, white hair/beard). He will want you to find Quinna. Go to the Witchwood and you’ll find her close to the entrance. Talk to her and she tells you she wants to find the Witch. Escort her to the Witch house. Be careful of wolves, they’re pretty much everywhere. Once you’ve escorted her, she will tell you she will find her way back to Cassardis on her own. Go back to Cassardis and report to Adaro.
No Honour Among Thieves [The Ruins of Aernst Castle - 6]
Speak to the bandit leader, called Maul. He will task you to either kill 10 of the female bandits at the Ruins of Heavenspeak Fort, or capture a deserter. The deserter can be found in Cassardis. If you go after the deserter, tell him to go back to maul and face his own death.
