We find the Emerald Ring on the left side of the castle. Then we meet Marduk, who tells this place is going to crumble promptly in a few seconds. So we have to escape out and then... We reunite George and Mary, but things are not over just yet. Marduk asks to meet again. So the next video we fight even harder enemies. Look forward to it. Side note, you could continue to train here before it gets destroyed but I did not. Oh well. -_-
