Eventually, you will find yourself in the Town. It's where most of the game takes place, stretching across 49 boards each with different landmarks and things to do. Over the course of the game, you'll investigate, wander, solve puzzles and talk to strangers all across the town. The story is told from the perspective of 8 different characters, each with their own unique content such as puzzles and cutscenes, all in different styles matching the character.
Each character is based on a particular element explained in the I Ching. Their personalities and actions all loosely revolve around elemental characteristics observable in the universe.
I'll give a brief introduction to each of the characters and explain what you will be doing as them.
The Artist: Sky
The Artist is a quiet man with an interesting agenda. As him you will go around the town to talk to the other characters, to put the mysterious plans into action.
Julia: Earth
Julia is a mysterious girl who is working with The Artist. She goes on errands for him, planting things and meeting people. She may or may not have a hidden agenda of her own. As you try to figure out what you're doing, you'll often need to pick up important items or go on little side quests to appease the other characters.
Toni: Lake
Toni is a sweet and adorable girl who loves making friends. She always has something nice to say to everyone she meets along her journey. She loves to explore The Forest, engaging with the fairies, and coming across mysteries. As her you'll skip around the town meeting friends and giving gifts.
Osiris: Thunder
Osiris is a writer and a scholar. He knows a lot about The Town and of the origins and purposes of the old altars scattered around. His journey is one of knowledge, and as him you will find yourself visiting the altars, referring to the numerous books in the library, and solving puzzles about The Town.
K-Rush: Fire
K-Rush is a cool DJ who is always in a hurry. He has an important party on his mind, as he's trying to promote it. As K-Rush, you'll run all over town, getting lost and asking for squares. He doesn't really care about the altars, mysteries, or Toni.
Merci: Mountain
Merci is a paranoid girl with schitzophrenia who somehow ended up mixed up in a multi-dimensional conspiracy. As her you will try to keep sane, avoiding cultists as demons keep whispering to her about the Crimson Eye and stuff.
Eliza: Wind
Eliza is a beautiful girl and a poet. She's dating K-Rush and her daily activities include reading and wandering carefree around the town. She knows about the party K-Rush keeps talking about and is excited to let other people know about it to. As her you'll be doing a lot of wondering and wandering, not too particularly concerned about anything.
Verona: Water
Verona's a sad girl. To be honest, I don't really know what I'm doing with this character at all yet.
