The most traditional Aasimar faction, they still worship the 7 archangels although due to the outside pressures the boundaries between the 7 sects have become less strict and all sects now live mixed together on the islands they managed to hold on to. The Protector Aasimar believe in everyone's core freedom, which includes the Fallen Aasimar's Atheism, and during the centuries of civil wars following The Reckoning they have fought on the side of the Free / Fallen Aasimar to defend them against Scourge Aasimar crusades more often than not.
The Protector Aasimar see it as their duty to protect their Home World so only extremely few of them have left their world for a life of adventure to protect the weak throughout the universe.
