After a few minutes and with great effort on his part, Torrential forced himself to stop cursing and calm down. 

It was still very clear that he wasn't at all happy about the situation in the slightest and his breathing was very heavy, but his gaze hardened as he glared at the befouled waters before him. Turning his head a little towards the two mares behind him, one bowing in the marshy filth of the ground they stood on while the other was frozen in fear, Torrential softened a little as he reprimanded himself for causing his two companions undue fear and stress. There was one lesson that needed to be taught here... could only be taught here. One that Celestia had foolish tried to deny and purge from the mortal world during the reign of her 'immortal' empire; The result of which he suspected was a chief factor into how badly the situation fell apart when she vanished without warning. 

"The world changes. What is considered fact today will be proven wrong tomorrow, the tyrant that ruled with an iron hoof will grow old and die and somewhere up in the mountains a boulder shifts position and a river is diverted miles away from the riverbed that had been its home for hundreds of years. Twenty years ago, Ponyville was flooded. It's hard to say if the war started because of the destruction of Ponyville or if it was destroyed because of the war, but either way innocent ponies died as the town was engulfed by water. No matter how one feels about it in hindsight, it happened and there is no force in existence that can or would change it. What happens stays happened. Maybe it isn't a fair system for those who get crushed in the gears, but it is the only one that works."

"I am not upset because Ponyville was destroyed. It happened two decades ago and nothing will change that so why bother? Nor am I upset with those who committed the act. War makes us do terrible things that seem important at the time but in hindsight were little more then meaningless tragedies. I'm upset because in the short sighted desire to wipe a town of ponies off the map, those who made this happen attempted to ensure that nothing would grow here ever again while leaving only a blighted, poisonous swamp in their wake."

"Where there is death, there is always rebirth." Turning his head back towards the befouled waters that marked the location that Ponyville once stood, Torrential nodded his head as he came to a decision. "Ladies, I suggest you find a good place nearby to set up camp. This is going to take a while." 

Without looking back, Torrential started to walk towards the water... and then started to walk [i]on[/i] it as if it was solid ground. He walked out a fair distance onto the surface of the foul lake before closing his eyes. When they opened again, his eyes glowed pure white. The water beneath his hooves started to glow the same white as his eyes, a cloud of pure, glowing white that was spreading out like ink being dropped into water and steadily growing by the minute. This wasn't as quick or simple as making a glass of water pure and safe for drinking, but the only real differences were in scale and time; Neither of which were really an issue for the Ailcorn of Floods.
