I had a feeling it was him. I will also say that given the fight is not to the death he could just refrain from using the more extreme abilities. As for Scion I can see him being able to fight with just some physical abilities. I would probably give him Perfect Body, The Force Tonfa as his main, and the Solar Staff as his backup. I see the dreamer being a adept sword fighter, but he probably can keep it non-lethal if he wants to.

So these three things.

[hider=Perfect Body #5]
[b]Perfect Body[/b]

In void one's perception of themself and their desires affects them greatly. Scion's desire to be in control of his body and perceived good athleticism earned him even greater control of his physical state. This ability allows Scion to manipulate his body to be able push itself far past its normal capabilities. He is able to select a bodily function and enhance it. He can only enhance something to a little above peak human or low superhuman,  and can only do a few functions at a time. Receiving less of an affect when he divides his attention. [/hider]

[hider=Force Tonfa #7]
[b]Force Tonfa[/b]

A black tonfa made of a strange light-less metal with a white crystal sphere on the top. This Tonfa, when struck or struck with, will collect kinetic energy, about twenty five percent, and store it within. This stored energy can be released at will be the user and be added or subtracted from other kinetic forces within the user's reach. This function allows it to enhance blows given, or reduce ones taken as long, as it has enough energy stored to do so. [/hider]

[hider=Solar Staff #6]
[b]Solar Staff[/b]

A five foot long black staff made of a strange light-less metal topped on each end by a white spherical crystal. This staff was forged by Scion and Dennis with their limited knowledge of the Void. At will this staff, when spun, is capable of releasing jets of flame and/or micro explosions from the ends of the staff. The staff is charged when spun and generates one charge per round or one every five seconds of continuous spinning. Takes one charge to release either five seconds of flame, equivalent to a flame thrower, or release a blast of force equivalent to a stun grenade. It takes two charges to release an instant ten foot cone of explosive fire out of one end of the staff. [/hider]
