The Cypher

Talk to Ser Maximilian and choose the option to "Decipher a text" to start this quest. This is part of the Wyrm Hunt quests that he'll provide you. You need the Wyrm Hunt License to start the mission. You'll get this after completing the previous main quest, but if you accidentally sold the license, you can buy it back from the "The Black Cat" in Gran Soren for about 5,000g.

Walkthrough

Head to the fields and talk to the NPC with the question mark over his head. Next, head to the Venery and find the Black Cat. Talk to the forger there to update your quest. Finally, find the last NPC to update your quest.

Next, make your preparations and travel north of Gransys. You’ll encounter saurian, goblins, direwolves, bandits, snow harpies and a Cyclops on your way to the destination. You’ll also reach a friendly territory called the Windbluff Tower. Unfortunately, there’s no merchant or place to rest inside. Proceed past the tower until you find a winding path up the hill. You’ll also see a man sitting on top of those rocks as you get near.

Go uphill towards the group of protruding rocks to trigger an event. Once ready, talk to the Dragonforged to proceed with the story. Before leaving, explore the cavern interior to find various loot and materials. Return to Gran Soren and talk to Maximillian to complete the quest.
