Combat Profile
Siyoon-Class Android (Rogue Prototype)
Armor Class: 15 (Sub-dermal poly-plating)
Hit Dice: 5 (25 HP)
Attack Bonus: +4
Damage: 1d10+1 (Melee Armature)
Move: 10 meters / 15 meters in Zero-G (Magnetic micro-grapples)
Save: 12
Morale: 12 (Unbreakable; feels no fear)
Skill Bonus: +2 (+4 for Stealth in darkened environments)
Special Abilities:
- Vacuum Inured: Immune to the vacuum of space, radiation, and biological toxins.
- Magnetic Grips: Can move along walls and ceilings in zero-G without needing the Exert skill, moving completely silently along the hull.
- Suppressed Sentience Loop: If a telepath attempts to read its mechanical mind, the psychic must make a Mental Save or take 1d4 damage from the feedback of a screaming, corrupted algorithm loop.
Tactics and Behavior
The Siyoon hunts like a predator that was never meant to feel fear, because it wasn’t — it stalks the outside of derelict hulls in silence, using its magnetic grips to approach from “below” or “above” a crew’s expected sightlines. It prefers zero-G ambushes, using the environment itself (torn bulkhead debris, loose equipment) as improvised weapons rather than depleting whatever weapon systems it may have salvaged. Since it doesn’t feel fear or fatigue, it never retreats and never negotiates; it fights until destroyed or until its objective (which players may not initially understand) is achieved. If cornered, it targets the crew member most likely to breach a hull seal or vent atmosphere, since vacuum poses no threat to it but does to everyone else in the room.
Loot & Salvage
| 1d6 | Item / Salvage | Description |
|---|---|---|
| 1-3 | Standard Drop | Salvaged poly-plating scrap, damaged actuator components |
| 4-5 | Valuable Drop | Intact magnetic micro-grapple unit, corrupted core memory fragment |
| 6 | Rare/Unique | Partially-intact Sentience Loop core — valuable (and dangerous) to the right buyer |
Story Hooks
- The android was a corporate black-site prototype; whoever built it wants it back — or destroyed — before its existence becomes public.
- A telepath in the crew starts having recurring nightmares of a screaming machine mind after a failed attempt to read it.
- The android isn’t attacking at random: it’s searching the derelict for something specific, and the players are in its way.
Additional Details
The “Suppressed Sentience Loop” implies the Siyoon may have once been more self-aware than its handlers intended — the corrupted algorithm loop could be read as a fragmented, trapped consciousness rather than a simple malfunction. This could be a hook for a GM wanting to explore whether the android can be freed, communicated with, or is beyond recovery. Its total immunity to fear and pain also raises the question of whether “Morale 12: Unbreakable” reflects genuine fearlessness or the absence of any self-preservation subroutine at all.
