You woke up in Amblerta with Tonsoria.
After regrouping with Moonflower and Furia Storm, you came across Apple Basket. To thank you for rescuing him yesterday, he gifted you a sailboat, and you offered him to join your party in turn.
The four of you then sailed to Furia Storm's home, where you met Queen Maelstrom. She gave you the philosopher's stone of legend, and asked you to find a way to destroy it. She and Furia Storm then left for Equestria to rescue the other sirens.
The next day, you were boarded and captured by Black Hound pirates. You spent most of the day in a dungeon, until Snap — the seadog you met earlier in Amblerta —, broke you out of there.
Snap brought you to her island, Wind Shepherd Village, where you stayed the night. Come morning, you met a travelling flock of harpies lead by Floga, and they agreed to take you to Midgard on their way home.
Once in Midgard, you met Novelty, a scientist who created an equinculus named Eleven. She hinted that in order to cross the Mists to Yggdrasil, you should first go under the capital city of Elysia.
The next morning, you sailed north to Norora. While on a quest to obtain warmer clothes, you befriended a dragon named Smoke. Together, you spent the evening working at the local hostel in exchange for an overnight stay.
You then set out to Elysia. There, you met a Cleric named Florette, who showed you the way to the underground settlement of the Undercity.
While in the Undercity, you met Bright Logic, Justice, and Rocket Rush who, along with Novelty and Eleven, agreed to help you cross the Mists on the morrow.
In the meantime, you spent the evening learning a little more about the Undercity, before calling it a day.
