Indigo announces her presence with a cough, even as she approaches the source of the sudden noise. How some kind of faceless glowing plasma-person coughs without a mouth is a mystery, but she manages it. At least she's covering her... area where the cough is coming out... with one fist, though it does little to stop the wisps of pink-purple smoke from drifting into the air.

"C-careful," she manages once she's done coughing. "There are some nasty critters that live 'round here, ya wouldn't want to attract their attention." But judging by the rainbow sword on her hip and the old-fashioned rifle on her back, she seems prepared for such an eventuality.
