Flames
The blue glow in the sky has died down and inevitably left a lot of people confused, especially those that were far off from the hanger where the scene occurred. At the weapons vault where Arsha and Sumi did battle, the latter stood facing Finn who had arrived on the scene some moments earlier.
"What was that surge of energy?!! It's weakened me slightly and I'm sure with the look on her face, it did the same too!!" Finn said with his eyes locked dead on Sumi. With his guess being spot on, Sumi had also felt the effects of the blue wave to the point that she tightened her fists to avoid being noticed that she was shaking.
"I don't know what that was but it has done something I hope is not long lasting!!" Sumi thought. Their attention had been stolen from one another for a moment but they soon returned to facing one another.
