What Skally said, but here anyway

He didn't know how was continued to be dragged into the merciless games of Liaison, how whenever the man called he was sure to pick up both of his swords and answer the challenge. A vein attempt to behead the man, perhaps, a chance to find some sort of weakness. 

Tsk.

He opened the manilla envelope knowing what he'd find. The Liaison had a fondness for the materia he called Dust, but it was really unimaginably small pieces of microtechnology that served various functions. Microphone, surveillance, and hyper teleportation devices.

Awash came a blue light, bathing him in a glow that resembled his chi manipulations. Oh Liaison was a douchebag. 

When his molecules arranged themselves and he was fitted back together, he was standing on a magnificantly sized black blob. He'd heard of this arenar before, quickly becoming popular. It had properties that allowed whoever was atop it to change it into any environment. At the end of the Blob, there was an expanse of space, blue as the unclouded sky at high noon. Across that space, another Blob, which served as the center was present. According to the rumors, it didn't change, serving as neutral ground for the particular battle. 

Craning his head, he could see that the center blob served as a focal point, and that he was on the Eastern blob in relation to the rest. There was one to the North, South, and West. Each was separated from the center by a mile of open space. And each, over the course of the battle, would come to the center as the primary battleground. A hand of God, so to speak, made the changes.

Taking a deep breath, he closed his eyes and envisioned what his blob would be. An open field of grass, swaying high in the gentle breeze. A small drizzle, with the sun at the very edge of a cloud. Itt caused his blob to increase in size by half a mile, but still it didn't force itself into the space. No, his blob would always be a mile from the center.

Satisfied, the Dust came back and he was transported to the center blob to await the other four.[/hider]
