From the designer:
The Narrow Passage is a a short Trophy Dark Incursion where you take your loved one's body to the final, thin barrier between the afterlife and their world to beseech the guardians of the dead to let your dead loved one in.
Requires Trophy Dark to play.
A note: This Trophy incursion has no treasure. Dig deep on why the PCs are engaging in these funerals for their loved ones. What will they do to get them to the afterlife? At what cost? Make it personal. The afterlife here is literally a zero-sum competition.
Content warnings: Death, aging, maggots, funerals, possession
