Hmph, seems I'm a little late to the party.

Quick question before I start posting and whatnot, are relics and any items of important significance apart of this cross-dimensional Earth? For example, considering I'm RPing Metal Sonic, do the Chaos Emeralds exist somewhere? And anything else of great power from other worlds present as well? Just curious in terms of story and plot.
