Masked Masquerade of Darkness

Basically, none of them should have left Rollo alone after he tried to take away everyone's magic. This is purely self-indulgent, but a little bit of backstory about this story. When I first play this cursed app (it is my fun nickname for it), my three favorites are Azul, Idia, and Malleus with my favorite movie being the Hunchback of Notre Dame. So, in a week or so, they announced this event with Rollo. You don't need to read the Twisted Hearts series for this, but this will feature two OCs where two will play a major part in the story .
With Rollo feeling hurt and frustrated for losing to the students at Night Raven college, he vows revenge. This consumes him to find a "maiden of pure heart" and to gain a new power to crush them. The darkness takes control of him to the point where it controls him and decides to kidnap many maidens across the land. Neige comes crying for help while Azul is depressed that he hasn't heard from Aquamarine. Crowley hears about this and tasks the freshmen to find the maidens at the City of Flowers. The rest of the students involved in the previous masquerade follow them to ensure they're safe, but this leads to a fiery clash. Then again, they shouldn't have left Rollo alone.
