Silva spent the night watching everyone, and there was one thing that showed: all of them were pissed, angry at losing their fights.
So they trained through the night, trying to get better, using what little health potions Silva provided to heal themselves.
Finally, the second day arrived, and they were all active and ready to fight. Sleep-deprived, but ready to move. But no abominations came, and nothing else.
So the day went on through morning till noon, and nothing happened. But all of them knew Silva; there was no way Silva would allow them to rest.
So at every single moment, they could not rest, their minds thinking about what could happen next or what attack would be next, and that was exactly what Silva wanted.
When it was a few hours past noon, their panic had reached the peak. All of them could not even sit down to fake a break; they felt like someone was watching them.
