NOTHING BUT THE goddess' eyes move as they flit down to the offered blade, and for tense seconds, it seems as though she is simply going to ignore it and leave. the idea of hand-to-hand combat makes her entire being hold its breath, but she is no stranger to putting aside her discomfort for something practical. she takes it, but her lip curls in a distant snarl as her spirit rests flush against the arcane metal -- she feels like a direct and opposite magnet.

and if you fail, i will finish it.
