stygian
Dark beyond measure
Stygian means extremely dark, gloomy, or forbidding—the kind of darkness that feels absolute and impenetrable: stygian depths, stygian gloom.
The word carries connotations of the underworld and death, suggesting not just absence of light but a quality of dread or hopelessness.
Literary and somewhat formal. (Capitalized Stygian relates directly to the River Styx.)
