Forum:Where are the centurions in Tales of Symphonia (number 1 for the game cube)?

So I bought a copy of tales of Symphonia dawn of a new world for the wii, because I really enjoyed numero uno (the first one). And the game starts off with, ".....*SURPRISE* their are centurions in this world." It has been a few years since I played the first one. I know that this is kind of a new story that runs into what the old characters are currently doing. But were centurions in the first game? or are they some convenient element thrown in that have actually existed WAY LONG AGO during the great karlon war.

Cuz what I understand is that Methos got his powers to end the karlon war from the summon spirits and the sword from krato's pact with origin. But now game two is saying he stole lord ratatosk's power, or borrowed it and abused it. and then he went to sleep, and Ratatosk is in fact just a summon spirit residing inside of Emil who governs centurions, the guardians of monsters?

Please guide me
