Penumbra

Penumbra is a corrupted fish-type creature encountered in aquatic locations affected by shadow taint. It is described in multiple localizations as a fish overtaken by dark forces; the Japanese source explicitly identifies the corruption as coming from Dark Energy. The creature gives off an eerie presence consistent with other shadow-touched fauna and is encountered in specific ponds rather than as a general open-water spawn.

Penumbra appears as a localized hazard and resource node in areas tied to shadow themes. It can be fished from waters in Shadowgate and from a solitary pond found in Fragments. These spawn points are the only documented natural sources for Penumbra; it is not listed as a generic ocean or river catch in available locality data.

Penumbra has limited interaction usefulness. Attempts to butcher a Penumbra at a Chef's Counter show no listed butchering yields in the available loot documentation, which indicates that butchering does not grant standard fish or meat loot the way ordinary catches do. Because of the lack of butchering rewards, Penumbra functions primarily as an environmental encounter and a fishing target for completion or themed collections rather than a practical food source.

• Spawning: fishable in ponds within Shadowgate and in a pond in Fragments.
• Description: a fish corrupted by Dark Energy, emitting an unsettling aura.
• Loot and processing: no recorded butchering outputs at a Chef's Counter (butchering table lists no items).
• Role: collectible/encounter creature tied to shadow-themed regions; not a reliable consumable resource.

Players seeking Penumbra should focus on the specific ponds mentioned rather than general fishing spots, and should not expect traditional culinary rewards from processing. Because Penumbra is a themed creature linked to Dark Energy corruption, it is best treated as part of exploration or lore objectives rather than as a source of regular in-game materials.
