SULLEN: dull or somber in sound or color; gloomy; showing irritation by quietness
Dove often mutters that she wandered into Sangfroid by mistake, though it's rather hard to notice. Dove, in general, is rather hard to notice; she speaks in a soft, hushed voice, and her footsteps are as silent as a stagnant pool.
It's worsened by the rumbling sounds of the Frigid Waterfall, but perhaps she likes it that way? It could be said that it is easier to be quiet in a place so always loud.
Even when she's not even trying to, she hides in plain sight, blending into the dust with the earthy tones in her coat. This disguise is only weakened by the sight of two violent grey eyes peering out from her hiding spot, seething despite their coldness; When Dove is against something, without words, everyone will know.
This subtlety, this quiet and careful power is why Eventide chose Dove as an Advisor, and despite appearances (or lack thereof), Dove is often said to be the whisper behind every booming howl of Sangfroid.
