A few decades ago, this royal family overstepped their rule, becoming reckless and oppressing everyone. In short, they became too arrogant with the power they held, which led to a revolt, and the royal family was dethroned.
These are the only survivors of the former royal family. These men survived and wanted to reclaim what they believed was rightfully theirs, at least in their minds. Lortad knew all of this, but honestly, he didn't care.
In his mind, when the Fallen God resurrected, this entire world would belong to the Fallen God and his followers—meaning him. Therefore, he didn't care about these men's thoughts and desires.
However, that didn't mean they were useless. The easiest people to manipulate are those with great ambitions because their goals often cloud their judgment, and that was exactly what Lortad aimed for. So he said, "Well, how about I help you achieve your goal?"
