Severus rose from the stool, starting to pace in a circle. "Yes, just a high-and-mighty lord. Dancing the dance, 'stomping on the little people'." He came back around, squatting before Vel and grasping him by the back of his neck.
"You forget what you are, Vel Brassius, what you were sent to that ship to do. We both know it wasn't to rescue slaves." For a brief moment, his face contorted in a flash of disgust. The first sign he possessed any emotion at all.
"Now, why don't I tell you where this grievance began. Some time ago I had moved to take remaining Venatori collaborators into custody, ones who had operated within positions of some authority." He squinted, looking beyond Vel, "These were people who intended to place our country in the hands of a Darkspawn. People who killed Imperial legionnaires across our southern border. Now, the execution of bag men, laborers, foot-soldiers, enslaved or otherwise, nobody cares. They're faceless, expendable..."
"But the men and women I captured, many of them were high-born lords and ladies. Magisters' children, or magisters themselves; born of storied pedigree and heirs to their great houses." His grip tightened, "They thought themselves above the law, above justice... that they could play it off as one big lark. I took them, against the wishes of the magisterium by which they would no doubt be coddled, because the price of treason knows no class or status of birth."
Severus relinquished his grip, briskly standing upward, "But I was waylaid. A new movement came about, pressuring the Archon to back away from the adjudication of these traitors. Put it to a vote, they said, reserve the sentencing to the fair hand and good sense of the Magisterium. The architect of this scheme? None other than the esteemed Magister Caius of House Vaellanius. At first, I wondered if he could be a conspirator as well, trying to save his allies. Yet the true reason was... so much more mundane, something all too familiar here in Tevinter."
Severus leaned down, hands on his knees, "You know what he told me, later? That he needed support from one of the traitors' father. For a 'small endeavor' of his."
He extended a finger, reaching out to prod Vel's shoulder in mockery, "And there it is. The old song and dance; the constant jostling for power. Who am I to inconvenience them in their little game?"
