This is a pickup of a home one-shot game we decided to extend into a PbP campaign. This game is not accepting new players at this time, we're just continuing with the players and characters we started with.
Most of the game was run off-the-cuff, with few notes, so I'll recap some basics, and you guys can fill in any and all details you remember. (Feel free to offer corrections if I get details wrong, I'm re-writing this from memory.)
Your three main characters were an active agent of the BBB, also known as the B3 (to differentiate it from the Better Business Bureau), jokingly referred to as the "Broke Budget Bureau," an angelic Messenger who was bound into a human body, and a dark elf/drow who is herself awakening to her own magical powers.
The characters were investigating a serious of unusual deaths in a small suburban town (Joesville?) that existed within a larger suburban sprawl. This town consisted of one main 'downtown' street, where most of the major businesses, including restaurants, a movie theater, etc, existed along, with the rest of the town residential housing.
The players had investigated each of the deaths, the first behind a theater, the second outside of a restaurant, and the third in a neighborhood front yard. The discovered a common element, a teenage boy named Jake, who seemed to be involved in each one, either as a bystander, or relative.
Jake, as you discovered, is an elf, recently awakened to his true supernatural heritage. He felt lonely, but could tell when people he knew were also had supernatural creatures within them, and would try to unlock that for some of his friends. Unfortunately, this seemed to backfire, as they wound up dead.
Trying to look into this, you discovered, at an underage-friendly club, an off-duty police officer who was also investigating things, whom you discovered was actually a werewolf attempting to hide the supernatural elements in the police files on these cases.
Attempting to summon and bind what you thought was the culprit, a succubus, at a nearby warehouse, you instead summoned a fire giant, a massive red demon, which attacked you and the werewolf officer. Jake was taken by the succubus, and you teleported away, accidentally leaving the werewolf behind.
Meeting back up with the werewolf, he managed to track Jake's scent to a Chinese restaurant at night, which was crawling with imps, dark spirits. Sneaking into the place, you discovered that the succubus was actually Jake's mother, whose death had been faked, not of her own free will. When he was born, she had been an elf (perhaps not yet awakened?) but in the last 15 or so years, she had accumulated additional powers, which had changed her into a succubus since then. She had been trying to protect Jake, but didn't know about the fire giant's motives.
From what we recall, that's where we left off. Please, fill in any details you remember, and provide your characters' names, details, and playbook mechanics.
