Endless Library Zone

When Love is Lost, all that remains is Hate.
Sonic finds himself in a strange situation hot on the
heils of Dr. Eggman, What he thought would be a routine rescuing of his friend Amy Rose soon becomes a near fatal encounter with the Changeling Queen Chrysalis. The vile queen manages to syphon the love in Sonic's heart hoping to become more powerful than before. But this proves to be a grave error. Without love in his heart, Sonic now mutates into a true nightmare known as the Hatehog. Struggling to control his inner darkness Sonic now must continuously shift between his two selves as he continues on Eggman's trail...

Tails and Sonic conclude that they will need to gather the Chaos Emerald to help reverse Sonic's predicament. Only problem is that the location of these Emeralds is now hard to pin down as there are 27 energy reading spikes across the globe, on top of that they only have time to personally investigae 7 of them whilst the trail Eggman is leaving is still warm....

ENDLESS LIBRARY ZONE
One of the sixth locations to investigate. Looks like a certain mad scientist forgot to cut off the super computer hidden in the icy mountains and now our heroes have a clear entryway to his network system. And thanks to the matter to data conversion tech installed it's just a simple feat to enter a virtual reality to travel along the countless lines of stored data and code.

POSSIBLE PATH MISSIONS;
Well, we found the computer room, nopw all we need to do is get into Eggman's central network and claim the last two Emeralds that he stored behind the network's firewall, I don't know how but hey they are easy pickings. [link]
There you are! I've been looking everywhere for you! Listen I know you are trying to get the Chaos Emeralds from Eggman but that Hatehog takes top priority right now, I bet if we go along to the core data storage we might find clues as to how to cure you of this inner demon. [link]
