(Fixed my end of the post concerning the Fxenidome's location)
Chariot poked his head out one of the broken windows of the abandoned building, seeing Vixy trudge through an outnumbered fight with the Rabid Mets while several of the citizens were running scared, some not even attempting to make a beeline for the Fxenidome entrance.
As he was contemplating moving somewhere else and finding a different problem to fend off, one of the Rabid Mets spot him and charge towards him, scheming to jump through the window and gnaw on his ankles. Not wanting his negative Blood of Swords to draw attention and rile everyone into attacking him in another blind assumption that he was the cause of this infestation, he thrusts his elbow at the oncoming Met, bashing it into another crowd of mets and confusing them into attacking each other.
Several more Mets began to surround him, all of whom smart enough to find the entrance and waddle their way in to find an ankle to chew on. Chariot twists his upper body away from the Mets while hovering his hands together and charging up another energy attack which he thrusts at the oncoming Mets, but instead of a straight beam, the energy became a 7ft sphere surrounding him and knocking back any Mets that slammed into it. Some tumbled into other Mets and provoked them to attack out of retaliation, giving the silver knight opportunity to leap out the window and climb up the brick structure to the roof where the rest of the Rabid Mets wouldn't reach him.
This would have been his cue to run off and find something else to exert his frustration on, but decides to stick around and watch the Fxenidome just to be sure the lone defender would be able to fight off the oncoming swarm until the rest of the Resistance shows up to at least try to overturn WilyII's fibbing scheme.
