• We learn of her in Scarlett's Adventure Timeline.

• Has always been one of the top minds in her field.
• Has "cultivated underworld contacts as well as the more 'legitimate' ones"
• Was offered a 'most secret' assignment in the Tanraga mountains in mid-267.
  • At start, she was communicating frequently with her family.
  • Soon the communications trickled off, eventually dwindling to nothing.
  • When communication stopped altogether, Allain decided to go find her.

• It was she who set up the automatic trace that attacked Scarlett's and Kurt's Keys

Speculation

• She is "C", the last operative in the Cube Theft.

Codenames "V", "Q", "K" and "C", were hired to do the Theft. They are tied to the deaths of Fran Mendling, Bernardo Holyoke, Pietro Salk, Monica Grand, Isaac Cymbalisty, Anna Heath --- but someone else got to The Cube first. Who? And Why? "We never held it, It was already gone."
