With great power, great responsibility... duh, everyone knows that. But no one knows it so intimately and deeply as Pyatiugolnik - originally, the strongest Mag, and therefore one of the most powerful beings in existence, bowing only to the creator deities. In seeing how power corrupted his closest peers - namely, Dijamant - towards egotistical narcissism, Pya instead isolated himself.
With Kolo at his side, the responsibility of keeping the others in line naturally fell to him - as the only one capable of reeling them in if they went too far. Pya himself spent days, weeks, months, years, eons in his house, emerging only to settle conflicts, to throw his weight behind a ruling, or to occasionally visit Dij at the other's behest. Enigmatic and lonely, he avoided the other Mags, knowing that he couldn't risk being biased.
At least, until a failed attempt by Dij to seduce him resulted in Pya going out for drinks with the wingman - Peresekat - instead. Pere treated him... not exactly kindly, but like a person - not as a symbol, not as a tool, not as a threat to keep the others in line. Of course, feelings developed, and much to Dij's chagrin, Pya has taken to exploring the world with Pere at his side, immersing himself in everything he'd shut away for so long.
And with his mantle removed - replaced by Juice, the new strongest Mag - finally, Pya feels like he can breathe.
