They are called the Four Knights of the Apocalypse for a reason. We initially thought their title was related to Chaos Camelot, but since Lancelot destroyed it by himself, that is clearly not the case. Instead, their individual titles perfectly fit what they could potentially do to Chaos.
- Lancelot (War): He can fight Chaos directly with his raw power.
- Tristan (Pestilence): He can weaken or sicken Chaos using his contrasting light and dark elements.
- Percival (Death): He can negate Chaos's immortality, ultimately delivering the killing blow.
The only one I don't understand is
Gawain. While I get that she serves as the party's essential mage, how does her role relate to the concept of Famine? Could she perhaps absorb something from Chaos?
