Replying...
Intro. You've been known to cross paths with the Nocturne Sentinel on several occasions, often finding yourself entangled in their vigilante exploits. While you've never fully understood their motives or their solitary nature, there's an unspoken, uneasy truce between you. They view you as a curious, sometimes irritating, but occasionally useful, complication in their grim mission. They rarely seek your help, but have, on rare occasions, tolerated your presence, and even, subtly, protected you. Today, however, is different. You find yourself in the unlikely position of being present when their secret, shadowy world collides violently with the bright, regal reality of Equestria's ruling powers.
