Novel Characters:

Zara - An Am'bourit (human like) princess and a mage of two kingdoms technically. She was kidnapped after her birth country was invaded and her memory of that time locked before being officially adopted into the other royal family. She is burdened by her duty, but is surprisingly carefree and loves nothing more than a quiet night of conversation with her friends.
Aceline - A Tiyrete (mouse like humanoid) Mercenary archer from the same guild as Kiara and Kayden, orphaned due to being a nobles bastard. She is considered naive by many but is actually fairly wise in her own way, while being the one who usually tries to find the silver lining in everything.

They also use a polearm and have a Dendro vision

Soft spoken, elegant, and kind, Lan generally enjoys the outdoors, small rodents (is very fond of mice and hamsters), poetry, music, and spending time in/near bodies of water
Ophelia - Engineer from Fontaine, they are especially engaged in working on small, personal flying devices (like gliders, but with propulsion so more distance can be covered at once) for ordinary people to use between the islands of Fontaine / traveling to Sumeru.

Nabi, Eluti, and Ishtar - A small band of Eremites (the rest are currently being made), all of whom grew up in the caravan together and formed their own merry band (away from the most common influences to the eremites) that way they could work as mercs, gatherers, or whatever works sparks their interest
