The circle of protection created by the wings of the What remains of the Saqalu. They still wield the awesome power they always did, but they are no longer… stable. More. Nothing harmful can penetrate it; four-winged Guardians are any magical beings with the primary drive to protect or guard. Unfortunately, they’re all a little crazy. More have been known to keep their charges alive and well in water, under spell-attack, in the middle of fires, and under hail of bullets.
Anything that attacks that simply ceases to be when touching the caim. It’s theorized the Guardian wings actually generate an invisible portal to some unknown dimension, where all the bad stuff just goes, negating pesky things like transfer of energy. Of course, that doesn’t explain how some things ricochet, but that’s yet another mystery.
Unfortunately, the Broken are mad, so any knowledge they once had about it is long lost or twisted.
