I want find out who killed Arenicos as well, then proscribed and outlawed then, but by doing so with the legitamcy of the Senate and People of Calradia; Maybe, I'll emulate the steps of Augustus, pretend be part of them and when the chances arrive turn the power to my favor and punish those who killed the old Emperor and then placing my supporters in power.
But, I don't think Arenicos was assasinated, the guy was old, maybe he had a stroke or heart failure and during his fall cracked his head, since the pool of blood.
His wife wouldn't have him killed, although she's a suspect, but she's the one with more to lose, since his daughter wasn't proclaimed heiress;
The Senate is also a suspect, but motivations? Only power nothing more and one of them could be Arenico's heir
Garios is the one who has much to lose, he was a ranker who urseped the purple, he has to win the war or he'll be executed
But, I hope he was assassinated, so my rp could work :p
