Momotaro

Background
Gnomes dwell in the woodlands, out of sight and mostly unseen. Gnomes are practiced at concealment and illusion, and skilled at hiding from all but the most trained eyes. The Executioner’s Guild of Assassins, by nature of who they are and what they do, are unknown and unrecognizable to outsiders, but their members are constantly looking out for new recruits. They see creatures that others might miss, but even among gnomes, one assassin took notice of one particular gnome as exceptionally gifted at concealment and offered to train him in exchange for his loyalty and to answer when called upon by the Guild.

Momotaro had spent some years travelling to different places to carry out assassination contracts, until he was called upon by the Guild to take on a special target in Frostmoor. Duty-bound to fulfill his pledge to the Guild, he could not refuse. When he arrived in Frostmoor, the target had disappeared--vanished without a trace.

While attempting to track him, Momotaro was led into a dark place, where the tracks suddenly vanished. A sudden coldness came over him; he had become Afflicted, and had no choice but to remain in Frostmoor. This choice was not borne of honor or responsibility -- an assassin could easily stealth and slip away -- but he believed the Guild had sent him to Frostmoor for a reason, knowing what the consequences might be. Momotaro resolved to stay until his task was complete.

Momotaro sold his services on the black market, and because the Guild had trained him to be streetwise, he came to know the power brokers in town and the important places, but still tried to remain as anonymous as possible. He would take both tracking and assassination jobs, and it was during one of those jobs that he first encountered a monk, Stelmaria. She came upon him and surprised him, and though an assassin should have been alarmed at being so easily spotted while concealed, Momotaro was impressed and felt that she was not a threat.
