Even though Rhode decided to rescue Erin, this didn't mean he could get to work immediately. Before he could do that, he had to handle some important matters. After all, unlike the earlier trip to the underworld, he would be heading to another world this time. As one of the Creator Dragons, it would be a bothersome matter if Erin were to vanish from this world. But he had his own ways around it. After Gillian and Marlene researched and analyzed the black pole, his younger sister also gave a suggestion: if he were truly heading to that unknown world, he must store his dragon essence in this world. After all, he was unlike Erin who was a representative of a rule and a second and new representative would replace her after a period of long disappearance. On the other hand, Creator Dragons were controllers of rules just like how a game could change its customer service officers and GMs, but never switch its developer randomly.
