Clashing domains

"Sir, are you ready?" Peter asked cautiously once the two of them got far enough from each other. Since they were going to test their domains, the starting point required them to invoke their domains in a way that wouldn't interfere with the other. 

"Let's get this over with!" Tom shouted, closing his eyes and pushing his will outwards. 

'The feeling itself is pretty weird,' Tom thought, suddenly feeling the presence of everything within a small circle around his body. Every gust of wind, every particle of dust, everything was within the sphere of his influence. 

"One more moment, sir!" Peter shouted over, still not ready with his domain. 

For a skill that would feel completely natural to use in a battle, it was pretty hard to invoke it without the heat of a fight. 

Thankfully, before long, Peter managed to pull his weight through.
