Born into House Charthagnion in Egorian, Ferrucio had a relatively staid upbringing for a noble scion of that particular house; he was introduced to his first devil at the age of five, and has been steeped in the arts of diabolism ever since
As he grew, Ferrucio was groomed to assume a place of power in his noble house
. Trained as a diplomat--and, if need be, spy--his tutors instructed him in the ways of gaining confidences as well as leaning on contacts for information .
One afternoon, as the teenage Ferrucio lounged indolently in his family's orangery, his idle contemplation was shattered by yells and screams from the main residence. By the time Ferrucio had run the hundred and fifty yards back to the manor, he could only watch in shock as a bone devil impaled Gerrick, the Master at Arms, on its wicked tail. The devil looked all but spent--but Gerrick appeared to have been the last line of defence between it and Ferrucio's father, who stood quavering on the stairs as the devil tossed Gerrick's body aside and advanced once more.
The scene inside the manor was chaotic: there were bodies and parts of bodies everywhere, and when Ferrucio stepped backward away from the horrific sight that confronted him, he slipped on the bloody floor and landed on his backside. Ferrucio was further startled when Elba, the family's resident arcanist--hired to protect against precisely these sorts of incidents--suddenly became visible beside him. Elba laid his hands on Ferrucio's head, spoke a few words of arcane power, and even as searing pain raced through Ferrucio's body, he saw the bone devil turn around abruptly before it winked out of existence. Then, he slept.
When he finally awoke, Ferrucio felt frail. He later discovered that Elba had, through some forgotten necromantic rite, tapped into Ferrucio's life force and used it to power his final spell, a banishment. Elba had saved Lord Charthagnion's life--but at the cost of Ferrucio's health . Further, Ferrucio's brush with the arcanist's forgotten magics had permanently changed him: he was now able to see lines of magical force binding all things, and his family--troubled--eventually agreed to send him to the Egorian Academy for tuition .
Elba, as it turned out, had been offered as a sacrifice to a summoned devil who had been tasked with uncovering the source of the plot to kill Lord Charthagnion.
Ferrucio--previously apathetic about most academic instruction--took to his lessons quickly and completely. He mastered conjuration magic easiest of all, but found divinations and illusions harder to comprehend
Some years later, after his graduation from the academy, his mother took him aside, sat him down, and told him that House Thrune had been responsible for the attack on them, all those years ago.
Ferrucio, confused, thought that his mother was dissembling, but she explained that the divinations conducted by the family and their diabolic servants had revealed this truth shortly after the incident--but that Ferrucio's father had failed to act in fear of retribution.
But now, his mother told him, was the time for decisive action. She wanted him to go to Westcrown, the old capital, where House Thrune's hold is weakest, and spend time there seeking allies. Grimly, Ferrucio agreed
Having made his way to Westcrown, Ferrucio adopts the name 'de Angelis' (mostly out of irony) and uses his social skills to inveigle his way inside a number of different groups of disaffected citizens, and quickly learns that something is afoot--something big.
Carefully hiding his spellcasting ability for now, Ferrucio seeks a rebel group he thinks might make a difference, and take him on the first step toward an overthrow of the government of the city.
If there was one word you could use to describe Ferrucio, it would be 'driven'. He sees devils as tools--like many in Cheliax--and it's his intention to bend his magical aptitude toward becoming an effective summoner of them. (In other words, angling toward the diabolist prestige class.)
He recognises that it's highly likely his soul is destined for Hell and he can be a cold, calculating bastard, but he believes that one or all of three things justify his actions: (1) the ends justify the means, (2) summoning evil creatures to do his bidding does not make him personally evil--as by unleashing these vile creatures he is actually working toward a greater good, and (3) if he pushes his capabilities to the limit, he might just find a loophole--some sort of salvation for his soul that will divert it from its present inevitable course.
I am looking to play Ferrucio with pathos rather than as a scheming, nasty, petulant spoiled nobleman. And he is Lawful Neutral, and intends to stay that way (rather than sliding into Lawful Evil, for instance). Despite his tendencies toward Good, Ferrucio does not at present believe he can transcend his upbringing and his basic nature.
Who knows, over time he may change to the point where he no longer seeks to become a diabolist, but that's the only thing he knows at the moment.
