Guild Wars 2

Elementalists summon the elements, Necros deal in the dead, Mesmers use the arcane. What source of magic are Guardians supposed to be pulling from?

“With the turmoil in Elona and the spread of the Order of Whispers into other lands, more Paragon teaching showed elsewhere in Tyria. These teachings melded with other traditions, and over time, the guardians and their abilities can be found throughout the world and among all the races. They are not tied to a particular race, philosophy, or group of gods but rather to a larger concept of proactive defense, of taking the fight to a foe and protecting those you fight alongside while appealing equally to humanity’s defensive nature and the charr’s desire to rule the battlefield.”

From the Wiki.

Guardians are a mixed Hybird of Monks and Paragons from gw1.

In GW1 Paragon was a class that basically yelled at people a lot they had tons of shouts and “motivated people from their charisma”. Monks were the magical healers and protectors. These two had a baby which also shouted a lot during the middle of the night but somehow retained magical powers without worshiping a god. (I don’t think a Charr guardian will be worshiping dwanya)

Guardians use the same power Monks used in GW1.

Their prayers to protect their allies are manifest into physical form.

In the case of a Charr Guardian, it would be towards their warband.

Actually, Guardians use a mix of Tyrian monk, Elonian Paragon, and Canthan Ritualist magic. It is empowered by faith – not necessarily in religion, so I suppose “willpower” is a better term, but “faith” is what Jeff Grubb said – and probably deals with spiritual power similar to Canthans, and if it pulls from the Bloodstones’ four schools it’d likely be the school of Preservation (what was believed to be the school for monks in GW1). It should note that while it holds practices of Tyrian monks, they don’t believe the power comes from the same source – at least universally. In the case of human monks in GW1, at the very least, that magic was claimed to come straight from the gods (hence “Divine Favor” “Smiting Prayers” “Protection Prayers” and “Healing Prayers” as the attribute lines), which isn’t so in GW2.
