War armors

"War armors? What are those?" Cassian asked, his curiosity piqued. He picked up a rusty sword from the ground, attempting to cover it with his Domain. After a moment of focus, he succeeded, hurling the sword forward with a green streak of energy, sending it crashing into a crack in the wall at high speed.

Cassandra watched the sword embed itself into the wall, her smile widening as she continued, "Well, these are ancient pieces of equipment found in many ruins, but no one really knows their full purpose. They're incredibly heavy, too—too much for most beings to wear. And they consume an immense amount of mana, requiring numerous mana stones just to operate for a few minutes. That is, until the Circle Warriors came along. Now, we can power them up using our Domains."
