'[Finn is] a place in the Unknown Universe that has the power to separate different aspects of a person.' -Red, Series II, Chapter 66

Place Type: Unknown
Location: Unknown Universe
Description: Finn was once a thriving planet, but it was led to ruin following the actions of a Sorceress. Bent on taking over the world, she set out to make an army by producing copies of herself. However, she accidentally cast the spell on the entire world, resulting in everyone on the planet splitting into their different personalities. A battle between good personalities and evil personalities ensued, destroying the whole of Finn.

The spell upon the remains of Finn still lingers, so anyone who visits it will split into the different sides of their personality. This is where the powers that be in Hell sent Thorn to attempt to recruit his dark side as their new leader.
