Star Wars Universe Roleplaying Game

Slyyyg

Slyyygs are massive slug-like predators that thrive in the damp, shadowed places of the galaxy: sewer systems beneath crowded spaceports, flooded maintenance corridors, jungle sinkholes, and half-collapsed ruins where moisture and rot never fully dry. Their bodies are thick and rubbery, coated in corrosive slime that allows them to cling to walls and ceilings and protects them from injury.

A Slyyyg is not fast, but it is relentless. It hunts through vibration and scent, waiting motionless above tunnels or around tight corners before dropping its immense weight onto prey in a crushing impact. Rather than pursuing fleeing targets, it controls space—blocking routes, collapsing advances, and forcing intruders into panic-driven mistakes.

When threatened or cornered, a Slyyyg expels a spray of toxic bile that fills confined spaces with burning fumes. Survivors describe the encounter as disorienting and terrifying: slick floors, choking air, and the sudden Ramming slam of a living mass descending from above.

In civilized areas, Slyyygs are dismissed as maintenance myths until they become impossible to ignore. On frontier worlds, locals know better. They mark tunnels with warning symbols and avoid certain routes entirely, understanding that a Slyyyg does not need to chase its prey—only to make the environment itself deadly.

Wildlife encounters in SWURPG hit different than firefights. Slyyyg doesn’t “hold ground” or “follow orders” — it follows instinct: territory, hunger, fear, or protection of a nest. Run it like a living threat: ambush angles, terrain advantage, and a clear “what it wants” that drives its choices every round.

Slyyyg in Play

Slyyygs favor tight, vertical terrain such as sewer tunnels, maintenance shafts, caves, and enclosed ruins. They begin encounters hidden on ceilings or high walls, opening with Crushing Drop to gain advantage on a Head-Butt that knocks targets prone and disrupts formations.

Once combat begins, the Slyyyg focuses on controlling space rather than pursuing kills. It positions itself to block narrow passages, knock enemies down in choke points, and force clusters of targets together before unleashing Toxic Bile Spray. The bile is most effective in confined environments, where movement is limited and visibility is poor.

If denied vertical surfaces or forced into wide, open areas, the Slyyyg disengages and repositions rather than fighting to the death. A Slyyyg retreats to ceilings, side tunnels, or flooded passages, returning once intruders are split, injured, or distracted—unless its nest or territory is directly threatened, in which case it fights with reckless persistence.

Adventure Hooks Featuring Slyyyg

• The Missing Maintenance Crew: A spaceport’s underlevels are closed after multiple workers vanish. Security droids refuse to enter the old tunnels, citing repeated sensor failures and movement on the ceilings.
• Smuggler’s Drain Route: A local crew offers a shortcut through a drainage system beneath a guarded facility. The route is real—and so is the Slyyyg that’s learned smugglers are easy meals.
• Nest in the Heat Exchanger: A settlement’s recycling plant keeps overheating and shutting down. A Slyyyg has nested inside the heat exchanger tunnels, and clearing it risks damaging the system—or getting dragged into the machinery.
