First Try!

"Hmm, I'll need to try out a small scale teleportation array, before going for the big one," Grey said while looking at the empty cave. 

He hadn't made one before, so he couldn't simply make one here then head to Eternal City, hoping it would work. 

He brought out a piece of paper and a brush and ink and started drawing array lines on them. 

Before trying them on the ground, he had the habit of first drawing the array lines on a piece of paper. He wouldn't be working with what others had previously made like for the communication device, instead, he would be trying to integrate his space element into a movement array. 

This is an array that, as its name suggests, boosts the speed of the one who makes it or a selected few while they are in the array. It's usually an array that covers a large area. This array is mostly used in wars.
