Phantom
Boss entry — details to be expanded.

Overview
Background
Phantom is a being woven from string, likely crafted by Grand Mother Silk. Phantom and Lace regard one another as siblings. Posted at the edge of Bilewater, Phantom plays the Exhaust Organ, venting steam and silk dregs that shroud parts of Sinner's Road in the fog known as The Mist.
In-game Events
Venturing through The Mist, Hornet hears Phantom's music echoing through the haze. Navigating the fog leads her into the Exhaust Organ, where pipes and valves give way to the main chamber. As Hornet enters, Phantom vanishes into vapour before reforming to begin the duel.
Phantom's final blow is always a parried strike, triggering a cutscene as Hornet and Phantom exchange attacks and rush toward each other. Choosing to parry allows Hornet to deal the decisive strike. Defeat causes Phantom to unravel in a burst of silk, leaving Hornet with the Cross Stitch Silk Skill.
After the battle, Hornet can ride a lift through the Underworks to reach the Choral Chambers, closing out Act 1. The Exhaust Organ falls silent, removing the pressurised steam from the surrounding pipes and dispelling The Mist back into Sinner's Road.
Behaviour and Tactics
The encounter opens with a steam column obscuring Phantom in the background, followed by a second column slamming down on the arena's left. Phantom emerges from the plume, and contact with that steam can strike Hornet for two Masks of damage in rapid succession.
