Once you met with Agent Peregran, you headed inside to find the artefacts located in the centre of the Museum of Knowledge. But Elyos Defence Troop Leader Kontesius suddenly appeared and attacked you. You chased him. While chasing him, you were able to defeat the Artefact Protector but found it odd that he did not react. Although you had your doubts, you arrived in the Library of Counsel where you saw the Elyos Agent pouring a powerful energy into the Artefact Core. Agent Peregran and the Artefact Protector reached you just as you were about to kill Kontesius and Ostia. They restrained the Elyos Agent. The seriously injured Elyos Agent retreated, and Agent Peregran and the Artefact Protector tried to stabilise the unsteady Artefact Core. But the situation didn't look good, and Abyss Rifts were created from which Otherworld Monsters emerged. While you repelled the monsters' attack, Agent Peregran successfully stabilised the core and closed all the Abyss Rifts again. But the Artefact Protector told you it will not remain like this, and there may be problems again in future. Agent Peregran said it was crucial to find a solution quickly.
