Mobius Prime (Nyx's AU)

The planet/universe in which every modern Sonic game has taken place on. Needless to say, it's taken a few hits over the years. From raging water gods, to blowing up half the moon, to alien invasions and staight up breaking apart, this planet has seen a lot. It's even seen some retconned timelines that no longer exist, alongside some confusing time travel antics.   Amongst the people who live on this planet (Both human and Mobian alike), is one cat known as Eternal by close associates. This AU mostly revolves around her involvement with Sonic the Hedgehog and his friends, as well as the ever-mysterious Shadow the Hedgehog, who Eternal spends much of her time following around for one reason or another.   Regardless of Shadow, however, Eternal always seems to find herself involved in whatever world-dominating scheme the ever-present Dr. Eggman has thought up, and is always around to lend Sonic a hand.
