The spike on top of the otherwise perfectly smooth ball pierced through Vaner's thumb as if his royal skin offered no resistance.
The same skin that could easily withstand slashes of swords and axes alike gave way to the simple spike that wasn't enhanced with even the tiniest shred of spiritual energy.
That alone spoke wonders about the technique used to create this altar, a technique that was long gone to the people of this world.
And then, right as the first drop of blood oozed out of Vaner's thumb onto the spike, the tiny runes that covered the entire surface of the altar finally made themselves known.
There wasn't any sound or cascading effect that would draw one's attention to the change. It only looked as if the single drop of blood got diluted many times over without losing the hue of its color, only to then fill countless rifts engraved slightly below the surface of the stone.
