Current Situation (For GM Reference)

What phase is it when the investigators arrive?

This depends on when the game begins. Possible starting points:

  • Early: Investigators board in Honolulu before departure. They have days to uncover the plot.

  • Midway: Ship is already at sea. Strange events are occurring. They have hours.

  • Late: Ship is at Point Nemo. The Rite has begun. They have minutes.


Astronomical Details

The Planetary Parade:

  • Mercury — closest to the horizon, barely visible

  • Venus — bright, unmistakable

  • Mars — red, ominous

  • Jupiter — massive, dominating the alignment

All four form a nearly straight line pointing down toward the point on the horizon where R'lyeh lies beneath the waves.

The Moon:

  • Waning crescent — provides minimal light

  • The night is dark, the stars are wrong


GM Notes

  • Use the timeline to create urgency

  • Investigators should feel the pressure mounting

  • Environmental effects escalate as the night progresses

  • The chanting should be a constant presence — heard but not understood

  • The final hour (4:00–5:00 AM) should be chaotic and desperate

  • Multiple paths to success — don't lock investigators into one solution


The clock is ticking. The planets are aligning. And beneath the ship, something ancient stirs in its sleep.
