Upon activation, Draco noticed that some energy was drained from the surroundings in order to facilitate the summoning. This was something he failed to notice during Luxia's summoning, because summoning a Light Phoenix would of course warrant big moves.
But theoretically, this meager manticore contract should not even make a twinge, but it certainly had a reaction even here in the Refinement God's Treasury. Could it be that the quality of ones summon had nothing to do with their own characteristics, but the available energy around?
Thinking like this, he was naturally curious to see what would come out of this. Since there was such abundant energy here in the Treasury, would the manticore be a Rank 7 entity?
Or even a True God?
Draco's endless greed was ignited, and logic fled him. If he were able to rub his last two brain cells together, he would easily be able to know that it was impossible for such a thing to occur.
