The Wulfenbach Stealth Fighters are first seen attacking the downed airship the Vespiary Squad defected to Mechanicsburg in. They are armed with weapons between short swords and large daggers which are heavily poisoned and wear what look like pistol holsters, but are never seen shooting. They wear black uniforms with red facings, a hoodlike hat, and asymmetrical red goggles. These, along with the owl wings on their cap badges, suggest that they normally fight under cover of darkness. Their training is nowhere near Smoke Knight standards, at least in daylight, according to Tarvek.
