| Suggested name | Wannweic |
| Planet type | Large hot gas giant |
| When viewed from Sweng, Wannweic can reach an apparent magnitude of -3, bright enough for its reflected light to cast shadows, and making it on average the third-brightest object in the night sky. The planet is named after the deity Wannweic, the bringer of destruction.
At this time it may appear as a bright star-like object, but is often far more difficult to observe than Sweng.
Wannweic is shrouded by an opaque layer of highly reflective clouds of sulfuric acid, preventing its surface from being seen from space in visible light.
The outer atmosphere is visibly segregated into several bands at different latitudes, resulting in turbulence and storms along their interacting boundaries. Surrounding Wannweic is a faint planetary ring system and a powerful magnetosphere. |
