While nobles don't age easily, it was rare for powerful nobles to have such a young appearance.
Since opportunities to accumulate magical power were somewhat limited, it usually took many years to build up power.

Or... they were talents deliberately raised by great houses, concentrating their funeral energies.
"Such a character just happened to appear at this time, claiming an empty city right next to where Arabion's army is? Something smells fishy, very fishy."
The war between two great houses in the Grey Zone twenty years ago had an enormous impact on the locals as well.
The number of commoners executed on suspicion of being spies was countless, and some masterless wandering knights were forcibly conscripted to die on the front lines.
