Io

"Shush, Ganymede."

Io chronologically is the first moon from Jupiter and the only of the Galileans to attempt to maintain tensions between the four.

Personality
In real life, Io is a special moon with a known volcanic system on it's surface. This is evident with Io's personality, which is intelligence and a hot-blooded personality at certain times. Io is the brains of the four, specializing in the geological and igneous side of the Archipelago. Despite this, he is also a mediocre architect for the Galileans.

Io can get quickly angry when improper usage of terms and words are used. This quickly turns Io from a calm and intelligent person to a sudden grammar gatekeeper. Frequent profanity is used during this phase.

Appearance
Io dons a dark yellow business suit that is missing a tie, but with a gold undershirt. The suit has a diamond appearance common in many designs of characters, which fluctuates between a dark yellow, yellow and light yellow.

In cases where Io is venturing beyond the Megisle, Io keeps a dagger in a pocket.

House Appearance
Io's house is in the shape of a two-floor trapezoid. It has no windows, and it's interior is mostly covered in scientific documents and the likes. Io's house is designed for at least five people, but it's equipped for mainly one. Io rarely lets any visitors in, the exceptions being Europa and Charon.

It is a bleak gray, and has material that resembles that of tinfoil.
