Part 1
At the end of the «Deep Sea Plunderers» quest the seven member party of Agil, Asuna, Klein, Kirito, Leafa, Lisbeth and Silica, along with Yui and Pina were brought back to Alfheim by a whale. After being dropped off at a beach in Sylph territory, the group pondered on about the quest. After Yui repeated the conversation between Kraken and Leviathan, Leafa explained that the Æsir were a family of gods in Norse mythology, but no one understood what the «Prince» was. While the group talked about the overwhelming power of the gods, Kirito got lost in thought about how Kraken and Leviathan seemed as if they had their own volition, comparing them to an NPC that he had met on the 2nd Floor, Kizmel. Just as Kirito decided to halt his train of thought, Klein remembered that he had ordered pizza, which would arrive in three minutes, while flying to Swilvane for a safe log out would take at least ten minutes. Kirito then offered to watch over his avatar until it disappeared so that he could log out on the spot. He then also offered the same to anyone else in a hurry to log out and everyone aside from Leafa decided to accept the offer. After all of their avatars disappeared, Kirito and Leafa took off towards Swilvane.
