Executives (Boss, Mother)
Palatines, Sentinels, Envoys
Adjuncts (The very lesser emotions)
The Adjuncts are possible Palatines (so regular emotions).
Those are the 'good' peeps, so the allies of the PCs. The corrupted are made of the Sins and the Corrupted Emotions.
The Seven Sins
The example emotions are very much correct, besides the Corrupted. They can be any regular emotion, just insane. For example, Triumph (a Senior) can become corrupted, but perhaps become something more sinister, like Subjugation or Liberation. It's like an evil undertone.
As for PCs, it's easier to listen what they CAN'T be for sure:
Mother, Boss, Seven Sins, Four Horsemen.
In theory, anyone can be any emotion/feeling/concept. It's definitely going to be whacky and a bit crazy, but I'm trying to make it as open as possible.
Let's just all pretend I know what I'm doing, okay?
