"What is this nonsense? A single man originated a floor raid and the tower administrator allowed his challenge? Just which lesser god decided to pick a fight with the Olympians?" Perseus asked in surprise, as a floor raid wasn't something that just anyone could trigger.
A floor raid could only be triggered by a force which the tower acknowledged as capable of having a shot at actually winning the fight, which was why Perseus automatically assumed that the individual triggering the floor raid had to be a lesser god, as only a lesser god could have a fair shot at taking down an entire floor by themselves.
