Your party first has the opportunity to recruit Princess Evangeline, who wishes to be called Eva, after rescuing her to complete Act II, Chapter 6 (Princess Evangeline). If you did not do so then, she awaits them near the bar in the Aman'lu Tavern. Head west down the ramp from the Aman'lu teleporter toward the Aman'lu Tavern and enter it. She's standing near the entrance side of the bar. Speak to her and ask her to join your party. Return to the teleporter and head for the Southern Vai'lutra Forest (South) teleporter, then speak to the wounded caravan driver Mylindril. Doing so will initiate her quest if you agree to do something about it now.

Use the nearby teleporter to go to the Western End of Arinth's Ravine. Head west along the main path into The Vai'kesh Forest until reaching the bridge. Turn west just before the bridge and follow the path along the edge of the chasm to reach the entrance to A Small Vai'kesh Cave. Enter and deal with the enimeies arrayed to great your party. You may encounter an An'tul Vai'kesh Seer Neophyte among other enemies on the way in. Walk back through the cave and up to the door in the rear and speak to the Vai'kesh Zealot. Princess Evangeline will tell him they've brought the required ransom in order to get inside. Once in, the lead Vai'kesh Zealot realizes no ransom's been brought and says they'll kill your party as a fight breaks out. Take out the half dozen or so Vai'kesh Fanatics plus the Zealot, then turn south and open the door. Go on through and take out the Vai'kesh Neophytes plus the Jailor in the next room to obtain the Bronze Vai'kesh Jail Key.

Loot the area in the western cell to the south before proceeding. Head into the next room and use the key to open the locked door. Enter the jail cell and speak with Eva's Royal Guard of the Northern Reaches. He tells them that Jessic is being held in another cave. On your way out, you can have your party check the room to the north for some treasure, which may or may not guarded by a couple of Vai'kesh, if your wish.

Head back out of the cavern into the Vai'kesh Forest. Return to the bridge and continue first south then east back to the Western End of Arinth's Ravine teleporter. Continue east from the teleporter until reaching a north fork, which leads to the entrance to A Large Vai'kesh Cavern. Enter it and take out the welcoming committee, then head north into the cavern and do battle with a few more Vai'kesh Zealots. You'll see a star to the west on the small compass, which is their destination. There's a ramp up ahead and may be an An'tul Vai'kesh Seer Neophyte and five attendant neophytes to battle at the top. Head up it then turn west and walk past the Big Chest toward the locked door. Speak to the Vai'kesh Zealot. Princess Evangeline will tell him they've brought information and say the phrase mentioned by the soldier in the first cavern. The door will open and the lead Vai'kesh Zealot will ask if they come in peace. Eva will say "Not a chance!" and here's another six Vai'kesh Zealots to dispatch. Head south then west and there may be an An'tul Vai'kesh Fanatic to battle plus there will be a battle with some Vai'kesh Zealots, a Seer, and the Jailor, in order to receive the Silver Vai'kesh Jail Key.

Enter the jail cell and speak with Eva's Royal Guard of the Northern Reaches. He tells them that he's been unconscious the whole time in captivity and Jessic is being held in yet another cave, but he has no idea where. He then departs to rejoin the other soldiers fighting at Snowbrook Haven. To exit, take the north door to obtain some treasure on the way out.

Once back in the initial room, you can ignore the door to the north, as there's no treasure behind it, just enemies to be fought for experience. Head back out of the cavern into Arinth's Ravine.

Return to the path and continue east, crossing a bridge, and continue until reaching a second bridge. Leave the path and proceed further along the ravine to the east. Continue east to find the entrance to the final cave. Enter and left click on the door to engage the senior Vai'kesh Zealot in conversation. He says no one's allowed in, whereupon the Princess kicks the door in as the senior Vai'kesh Zealot shorthly thereafter asks how she could have kicked the door in. Here're another half dozen Vai'kesh Zealots to be dealt with. Head west and battle the Vai'kesh Zealots, Seer or perhaps an An'tul Vai'kesh Seer, and Jailor, in order to receive the Gold Vai'kesh Jail Key.

Return to the initial room and this time open the east door. Enter and turn north and head to the end of the area to finally find Jessic's cell. Left click on the jail cell door to open it using the Gold Vai'kesh Jail Key.

Enter the cell and speak with him. After a grand reunion of the two old friends, Jessic heads off to Snowbrook Haven and Eva remains with your party. Loot the Big Chest next to him and exit the cavern as you see fit. Thus ends this quest.
