Red

Red, also known as The Knight of Shadows, is the fifth boss of the game as well as the seventh party member to join Colt on his adventure. He is a man in black and brass armor and holds a sword on his right hand, which contains a scar.

Lore
He and Amelia met in an unknown amount of time before Luna's journey. However, during Luna's journey, Amelia had a biking accident and died. He then died in his fight with Luna, but he got revived a few years later by an unknown person.

Amelia
Amelia is Red's best friend and love interest. The circumstances leading to their meeting are yet unknown (but will be fleshed out in a prequel to MOON), but it seems to have been a few years before Luna's journey. After a biking accident, she died, but still follows Ender as a ghost. They have deep feelings for each other and promise to never leave each other. Their relationship is based on the real life relationship of the two who own the characters.

Queen Mo
Queen Mo met Red around the time the latter met Amelia. They grew to be really good friends ever since, to the point that the Queen appointed him as her royal knight.

King George
King George met Red when the latter was travelling around. They aren't exactly the best of friends, but they still are. The king does care about him, though.
