I thought about arson, but Fortune said it right: that's for the Halloweeners.
Here's a short summary of what happened: Adriel was allowed to choose between a beating by the rest of the gang, being "sexed in," killing an enemy of the Ancients (a troll called Torgo) or tagging Humanis' HQ in Renton and bringing back proof.
Adriel immediately rejected being sexed in, as it would have reduced her hard-earned rep to damn near zero. She didn't want her rivals in the gang to get wrong ideas (or see how tough she really isn't), so out goes the beating too.
Tagging Humanis looked like fun, so she chose that. Lucky me, I'll be able to introduce the players to Lord Torgo later on.

Using a disguise, smarts and good ol' Physical Mask, Adriel infiltrated Humanis's HQ and managed to make it into Karl Brackhaven's office. While looking for an object that could be used as proof, she had to hide when Brackhaven came back, bringing along his nephew, Kenneth. Both men discussed next year's elections, with Karl angry that Kenneth had decided against running for President. Kenneth's explanation was that President Steele seemed too popular at the moment, especially after giving citizenship to Dunkelzahn. "Had things been different, I'd be there, but I'm not burning myself against Steele."
The guys finished their coffees and left, leaving Adriel with a juicy bit of information. She tagged Karl Brackhaven's office and took her proof: a picture of Karl, Kenneth and little Tiffany. After that, she escaped as quietly as possible and returned to the Ancients. The gang held a mock Rite of Naming ceremony and officially welcomed her into their ranks.
