It has been two weeks after Chrysalis, Tirek, and Cozy Glow took Nighdrak in as their new ally, and they been trying to set their plan with Grogar's bell in their hooves/hands. Cozy is feeling something between Nighdrak and herself, Chrysalis is starting to talk to Nighdrak more than her log, Tirek and Nighdrak just do 2 hour hang outs, and Grogar... well, he doesn't like Nighdrak one bit.
However, nopony and no one ever knew what Nighdrak had been up to since his stay in the lair. Even though he's apart of the trio's plans with Grogar's bell, Nighdrak had been waiting impatiently to get his vengeance on Luna and her new friends, and when Cozy accidentally releases Nighdrak's other side... the plan is ensued.
