My theory is; after the Battle of Pendraic, Neretzes clan was humiliated and lost it's influence and seeing this, Arenicos found the opportunity and claimed the throne. Penton felt extremely humiliated and saw this as an insult to his clan and himself so he decided to poison Arenicos. He may have thought to himself "If Arenicos dies, I'll be able to inherit the throne without resistance and senate will have to choose me." but this failed and he started a civil war trying to make himself Emperor. He hated it, but he had to pick a side so he chose Lucon. We don't know why he chose him but it was a wise decision to join Lucon instead of starting his own faction. He didn't risk his fiefs and his reputation.
