Andr0m3daFirst QuestYou need to find Camila (bindstone guard) at Caronia’s tomb bindstone located at Varrylon.
Second QuestAfter you chat with Camila, you need to kill a boss named Boyton Haraford located near southwest of Varrow Forest bindstone. Varrow Forest is at east of the Varrylon map, Geizan map. From Caronia’s tomb, follow the route and walk to the east. You will arrive Geizan map.
Keep walking to the east at Geizan map. After you cross the bridge, you can see there is Ursa mage at your right hand side (from character sight), and Boyton is over a hill behind the Ursa mage, surrounded by paragon guardians. Although Boyton Haraford has an aura, he is easy to kill.
After killing Boyton, hand in to Istvan Baileys at Einhoren Town Castle. Istvan will ask you to have a conversation with Fers Hahnt, just outside the castle, he will ask you to talk to Godrich Haysbert, to the right of the Castle, and he will ask you to go back to Istvan Baileys inside the castle.
Then "Secret Investigation Mission" Go to Caronia's Tomb and open a box IF YOU ARE IN A PARTY YOU WILL HAVE TO LEAVE PARTY TO OPEN THE BOX or you will have to do the quest again.
Last Quest "Revealed Truth"This last boss is located at Varrylon map aswell. It is located at the small island, south-west of Pine Plateau bindstone. Look on the map and you can see a yellow dot with “3rd water element”, that is the location of the boss. This boss is surrounded by 3 beholder shape level 1 magic mobs. Kill all 3 of them and then the boss. This boss takles a while to kill but it only hurts you a bit compare to the 3 level 1 magic mobs.
