As of today, the first Darkus Eclipse side story has begun. It is called The Fiend War and here is the summary:

Tensions rise between the Original Digidestined and the Bakugan Battle Brawlers in the wake of the hotel attack. Meanwhile, the Cult's elite Fiend Guard make their move against their enemies so they can secure the Infinity Core. Against an enemy that neither group can prevail over alone, will the heroic factions be able to set aside their differences against a common enemy or is the world doomed?

There it is, the Prologue is a bit short but I look forward to pushing through the story.

Before I go, I have answers to some questions:

Warrior Werewolf: To answer your question, Impmon is coming back sooner or later, I just haven't figured out when and how.

Queue44: While I agree that your thought would be amazing to get back at the Digidestined, i have an even bigger slap in the face planned for them. I won't spoil anything but, it will happen around the time of the second side story I have planned for Darkus Eclipse.

Tank you all for your support of the story, enjoy The Fiend War!
