Okay I have been reading the stories for several Dragon Quest games that I've played, and I have beaten Calasmos in DQXI, so I know about the fact that DQXI comes before DQIII. What I'm thinking of is the fact that since DQVI came before DQIV and DQV, maybe it came before DQXI too.

Okay here's my reasoning. in DQVI the Zenith dragon is an egg that is soon to be hatched. DQIV he has hatched and is extremely powerful but not completely powerful. DQV he's more powerful (after he's back in his dragon form) than in DQIV. what if in like a millennium after the events of DQV, the Zenith Dragon takes the name Yggdragon when the demon Calasmos reveals himself to be the ultimate evil that (in my speculation) created Rhapthorne, manipulated the mind of whoever created the Secret of Evolution, and created Orgodemir to battle the Yggragon's right-hand man, The Almighty. Then after realizing that the only way to consume the world in darkness would be to fight the Yggdragon himself, thus resulting in the events of DQXI and everything afterward. what are y'all's opinions on my sketchy speculation?
