Julius 'July' Charlton
The pall of smoke was visible above Trost even beyond its curtain walls, too thick for any kind of celebration and too ominous to merely be the result of an accident. Julius stood atop the broken wall, having arrived with the returning Survey Corps to find that in their absence the Wall had been breached and then sealed.
Below them, by the boulder with which he had sealed the Wall, the Mysterious Titan kneeler and it's Shifter emerged from the nape, exhausted from his efforts. Elite Garrison soldiers died in droves all around him in the remnants of the square, doing their best to fend off the Titans attracted to their position. Two Cadet were trying to help the Shifter free, trying to get him to safety but the Titans were too close.
Captain Levi was gone before anyone noticed, faster than anyone else with the Gear and killing the closest Titan to the trio. The others stood there, still shocked by the destruction they had returned to, before gathering their wits and flooding down from the Wall to return the slaughter the Titans had inflicted on the defending soldiers.
Julius' attention remained on the unknown Shifter as he barrelled downwards, ahead of most of the Corps as he entered the fight. He took an unsuspecting Titan on his path down, hooks firing into one of the buildings on the other wide of the square and turning his downwards momentum into a low, swinging arc; his blades biting through its nape and dropping the shambling monster instantly.
The tide turned with the arrival of the experienced Survey Corps, their soldiers used to fighting Titans more than those of the other organisations, and they tore through the Titans threatening the remnants of the Garrison force who had come with the Shifter.
Julius paused atop the building which offered him a convenient vantage point, watching the Shifter as he was helped from his Titan form. It seemed that the moment they had been waiting for had finally arrived and so he targeted his gear and moved off in search of his partner to discuss their next move.
