WE NEED LORE FOR THE FRICKIN JUGGERKNIGHTS SO I STAYED UP ALL NIGHT MAKING MULTIPLE THEORY AND LORE AAAAAAAAAAAAAAAAAAAAAAAAAAAAA
1: Maybe they are speartons that were petrified by Medusa and she did some random crap to make them juggerknights or something.
2: They were marrow kai that wanted more power and were tired of being in the backlines even tho they have hands that go out the ground.
3: They are spirits of a dead nation that was resurrected to wage war and do war for medusa.
4: I AM STILL THINKING AAAAAAAAAAAAAAAAAAA
