Main Story Quests
Welcome, Source Hunter! This section will guide you through the critical path of Divinity: Original Sin, ensuring you uncover the mysteries of Rivellon and confront the Source threat. While exploration and side quests are highly encouraged, this walkthrough focuses on the essential steps to progress the main narrative.
Part I: Cyseal and Environs
Your journey begins in the coastal town of Cyseal. The immediate goal is to investigate a murder and establish your presence as a capable Source Hunter.
The Murder Investigation
Upon arriving in Cyseal, your first main objective is to investigate the murder of Councillor Jake. This quest will introduce you to key characters and the core mechanics of the game.
- Initial Steps:
- Head to the crime scene, located on the beach just outside the Cyseal gates. You'll find the body of Councillor Jake and a crowd of onlookers.
- Speak with Captain Aureus near the crime scene. He will officially task you with the investigation.
- Examine Jake's body thoroughly. Pay close attention to the dagger found near him and the note on his person.
- Use your Perception skill (if high enough) to spot hidden clues around the body.
- Gathering Information in Cyseal:
- Visit the Mortician's Office in the western part of Cyseal. Speak with the Mortician, Roberts, about Jake's body. You may need to persuade him to allow a closer inspection.
- Locate Esmeralda, Jake's wife, in the King Crab Inn. She is a prime suspect and will provide conflicting information.
- Search Esmeralda's house (located near the market square) for clues. Look for a hidden cellar entrance and a bloody dagger in her wardrobe. Be prepared for a confrontation if you are caught.
- Speak with the various townsfolk. Characters like Madora (found in the King Crab Inn) and Arhu (the cat, found in the Cyseal Legionnaire Headquarters) can offer valuable insights or join your party.
- Consulting Arhu:
- After gathering initial clues, head to the Legionnaire Headquarters in the center of Cyseal.
- Find Arhu, the magically transformed cat, on the upper floor. He will provide crucial information about the nature of the murder and the involvement of Source.
- Arhu will direct you towards the Lighthouse, suggesting that the undead activity there might be connected to the murder.
The Lighthouse and the Undead
Following Arhu's lead, your next major objective is to clear the Lighthouse of undead and investigate the source of their appearance.
- Journey to the Lighthouse:
- Exit Cyseal through the eastern gate. Follow the path south along the coast.
- Be prepared for encounters with various undead enemies, including decaying zombies and skeletons. These can be challenging for low-level parties, so ensure you have healing potions and appropriate combat skills.
- Clearing the Lighthouse:
- Upon reaching the Lighthouse, you'll find it overrun with undead. Engage and defeat all enemies in the vicinity.
- Ascend the Lighthouse tower. At the top, you will encounter the Lighthouse Keeper, who is now an undead ghoul. Defeat him to secure the area.
- Examine the Lighthouse Keeper's body for a key and a journal. The journal will reveal disturbing information about the Source and its influence.
- The Cave Entrance:
- Near the base of the Lighthouse, look for a hidden cave entrance. This cave leads to a new area with more undead and further clues regarding the Source.
- Proceed with caution, as the enemies within are often more formidable than those outside.
The Black Cove
The cave near the Lighthouse leads to the Black Cove, a significant location for advancing the main quest.
- Navigating the Black Cove:
- The Black Cove is a sprawling dungeon filled with various traps, puzzles, and powerful enemies, including Orcs and more advanced undead.
- Keep an eye out for pressure plates, tripwires, and hidden switches. A high Perception is invaluable here.
- You will encounter a large group of Orcs guarding a crucial passage. Consider using crowd control spells or environmental hazards to your advantage.
- Confronting the Source:
- Deep within the Black Cove, you will eventually reach a chamber where you confront a powerful Source-infused enemy. This encounter is a significant boss fight.
- Utilize all your party members' abilities, focusing on elemental weaknesses and status effects.
- After defeating this foe, you will uncover more about the Source's presence in Rivellon and the true nature of the threat.
