Must a son answer for the sins of a father he never knew?

Aegis was born a cambion in the infernal city of Inanitas — a place where fiends rule, cambions scrape by, and the only law worth respecting is coin. Freedom is expensive, and Aegis has only one way to earn it.

Bet on the right champion.
Collect the silver.
Stay alive long enough to buy his freedom.

Then an Eldari necromancer enters the arena.

To Aegis, the man looks less like a monster and more like an opportunity — a champion worth following, manipulating, or selling information about.

But when the necromancer sees the boy, he sees something else.

Hope.
His son.

The closer Aegis drifts toward the mysterious Eldari, the louder the whispers around him become.

Because the boy chasing silver may be tied to something far older than the arena.
After all, cambions are born from fiends.

So how could Aegis possibly be the son of a Paladin?
And if that is true…
What sin is he meant to atone for?
