The dead bodies of all prisoners had been collected and were about to be disposed of, thrown into space.
Under the conditions of space their bodies would be destroyed, but it would still be a less bad treatment of their cadavers than what the Colosseum did.

It was one more of Talho's ways to lower costs, not that he needed it. Besides just as Void Beasts could be nutritious to warriors and mages, the same logic was true the other way around.
So not only did he cut down costs of maintenance, but it also helped the beasts keep some level of strength.

Talho was the first to leave, not bothering with the etiquette or being too courteous with the guests. He had already been more than so when they arrived after all.
