The quest is open to both members and free players. To start, go find Gudrik’s house in southwest of Taverley Bank and ask Gudrik about Ashdale. Gudrik will describe the queer thing he finds recently, that cargo ships sailing to Ashdale return untouched. The sailor on the ship claimed Ashdale was empty. Gudrik needs your help to find out the reason. You shall accept the quest and go to west dock boarding a ship.
When you land on Ashdale, make your way to the town by following stairs in north. You will then look for a house with lights on. In the house talk to Lucy and you will learn what happened in the town. Few days ago, a mysterious creature came and took almost every people away. To investigate, you need to reach the other side of the island. Ask Lucy for help and she will point out the way: there is a storm drain back of her house. You can find an entrance there to the town sewer system, via which you can reach your destination.
Follow the Lucy’s guide and enter the sewers. Walking through the tunnel, soon you will see a big room and be shown a cut scene. Then a Crassian scout, who matches your combat level, will attack you. Watch out not be killed or you will have to start over at the entrance of the sewers. If you kill it, keep moving forward until you meet another Crassian scout. Kill it again and climb up to the ground. You are now at the other side of the Ashdale.
There is a bridge at your west side, cross it and go south. Soon you will encounter two more scouts guarding a gate. Kill them to open and enter the gate. Once inside you need to find a book which describes author’s intention of building a secret house under Ashdale. There is a hidden staircase under the Bust. Go down through the staircase to enter a big cave, where another two scouts awaiting for you to kill.
