Voices in the silence

You probably have met Umbra, you simply don't remember her. She seems like any other young woman: smiling, accomplishing nothing more than the ordinary daily life routine, not talkative enough to peak your interest.
What you didn't know though, before forgetting her, is the secret she's hiding. In the silence that you hear, she can perceive their voices. Depressio, Sollicitus, Culpa, Solum, and Vita... all five of them speak to her. Some yell, and some whisper, but they all hold on to her.
