Mesonox

History
Everyone knew when Death was coming, but Mesonox was intimately familiar with the terror that such a being exuded. The only thing that kept her here, hiding amongst the foul residents was her sense of purpose. The need to make a difference.

She remembered the first time she'd escaped, how her flickering light was millimeters from being devoured- how she felt the chilling touch of smog claw at the tips of her little wings, eating away at her very being. To this day, the edges bore the rotted out pocks and scars of just barely escaping with her life.

The roiling cloud of black smoke filled the entire tunnel, like a great devil's train tearing down the tracks. A pair of cruel hot-coal eyes locked on to her luminous tail. Haggard breathing, twisting into a low chortle that sounded like his throat was barely held together, "Fly, fly little glowbug. Lest I snuff your light forever."

She got the feeling that he was playing with her.

There was no doubt in her mind that he could have caught her by now. He was simply tormenting her for his own amusement, wispy claws making lazy swipes at her, not matching what she knew. The precision of something that tore your very self from your body, your energy, your light- it couldn't be understated. He was using her as entertainment, feasting on the sound of panicked panting.

It was only after she squeezed into a crack that he stopped, cornering herself into a little cranny within the red jasper walls. Her tiny heart raced, watching as the crimson of his eye swelled within the opening, peering down and dousing her in a bloodthirsty glow. The sound of laughter rattled the crevice, and she dared not try to move for hours- long after he'd left, having grown bored of tormenting a mere morsel.

The only reason she was alive right now was because she barely counted as a snack to him. He had grown full and complacent from the spoils of the Pit's challenges, no longer needing to chase every scrap of life he could get his talons on. And if he wouldn't actively seek to devour her, then... perhaps she could use that to her advantage.

From then on, Mesonox got more adept at avoiding the ever-ravenous god, and used it to her advantage to assist wayward souls in escaping the Pit altogether. To die, and die again, body and soul consumed by the denizens of the Pit was a fate she wished on nobody.

So she would do what she could to make a difference.
