A Darkness Rising (Cookie Run AU FanFic/Story Thing)

Pancake Cookie, Creme Puff Cookie, and Pilot Cookie are still wondering where Roll Cake Cookie (Pancake's slightly older brother) has been all these years. They're losing hope that he could still be out there, then weeks later, he returns. But he isn't the Roll Cake they used to know, in fact, he barely had any joy left after being reunited with his family and friends. He seemed....depressed.... Then, he got a curse that could either be cured or turn him into a monstorous creature with no intentions of good, or, he could end it all. Stay tuned to see what happens!!
