Seung Un Explosive
The Seung Un bomb remains hidden, but its nitroethene traces trigger filter alarms and force Clarissa to murder the technician who recognizes them.
Story so far
Clarissa Mao molds the dense, heat-softened explosive around a reinforced Seung Un junction and embeds a four-millimeter ceramic-contact detonator. As it cools, the putty hardens and fades from bright green to gray, becoming visually inconspicuous enough to survive her false maintenance inspection.
It is not chemically invisible. Stray molecules enter the destroyer's environmental system, and Ren finds high-energy nitroethenes in the air-filter profile with a ninety-percent match to moldable mining explosive. The levels remain steady rather than increasing, but he plans to alert ship security. Clarissa kills him before the report can leave their team, turning the device's overlooked residue into the first direct human cost of preserving the bomb.
Appearance
The device is dense gray putty hardened around a reinforced junction, with a tiny black detonator embedded like a tick. Invisible airborne traces of nitroethenes and related compounds collect in environmental filters.
Role
The explosive is the concealed proof for Clarissa's counterfeit Holden attack, now dangerous not only to its target ship but to anyone whose technical work detects it.
