The Invalesco are an elite group of Mysterium researchers whose sole mission is to defeat the argons. These are no ordinary researchers—they’re doing “field studies” in an active war zone. The Invalesco are soldiers of science. They use their minds to fight the war with the argons, and you can help them by offering your smarts, strength, battle skills, and agility. Get to know this TERA faction in the Invalesco game guide. They’ll make it worth your while.
