Green...men...rule...really.
That Lavos Battle Scene pic is effing awesome!!!
Yeah, but it's called Magus' Castle...Not "Ancient Mystic Castle" or w/e...I guess I'm just going on what I see, but w/e...
Simple, Janus used his powerful skills to use it as his own.
Also note, the castle looks WAY old. Probably like 100 years old and half in ruins nearly. Which would explain why it was...ancient.
Also, it was called Magus' Castle so the player knew where they were going!
