Leo followed the guards deep into the stronghold. As they were walking, they walked past a cellar very similar to the one Leo was chained in. He peeked into it and saw that the people there were completely silent even though all of them were alive.
They were all too weak and afraid to make a single sound. The cellar had a total of 74 people in it, which meant it was also probably stripped out of its best candidates like his cellar.
As they walked more, Leo started discovering that the number of Aura Knights was increasing. The number of cellars they crossed also increased one by one. Each of the cellars were manned by two guards each.
