While Morrigan wasn't as enthusiastic about destroying the Reapers as Maia was, she was still enjoying unleashing her magic on something that deserved it. Though the more Reapers she saw, the more Morrigan thought she should put her dragon form to good use.
Or potentially that new gryphon form she'd been secretly working on. If Maia wanted to 'nuke from orbit,' as they said, Morrigan would engage that form. After all, the Grey Wardens of old rode gryphons into battle.
At Maia's warning, Morrigan spun around, unleashing a cone of cold to slow the creature's approach. She leapt back, then hit it with a fireball. Luckily, it was just a husk, so it went down and didn't get back up. "I am beginning to think we need a little more fire power here." Especially as she could see bigger Reapers around the area.
