The demon king
The demons were a source of fear for the Skullys, especially those like Anon that could barely fight back against them, not unless they were large in number. However, getting anyone to work together in this world was incredibly difficult.
Even before Immortui had arrived, all of the inhabitants were at each other's throats. Killing was an everyday occurrence amongst each other. There were no laws, and only the strong survived.
The idea of teamwork, or armies, was ridiculous to them. Looking back, Skullys wondered if maybe that's how their whole universe had been taken over so easily, even though they had powerful beings all over.
It was a surprise that Anon managed to convince Ekeke and Tuni, but others had rejected his offer. Still, it was a change that Anon could see, as everyone had a common enemy. People were starting to come together, but it was a little too late.
