Vaclav Havel

His special ability is to optically camouflage himself, as well as seemingly take flight. He is one of Cardinal Sforza's most trusted friends, and apparently has been by her side for at least 10 years prior to the story line. He usually spends his time by Lady Caterina's side, but occasionally goes on missions like the other members of the AX.
Named after former Czech President.
