Secret Vault of the Windswept Island

From the publishers blurb:

On the lonely Windswept Island a death cult's dungeon hides the path to an extraplanar vault with a macabre ritual. Within that dreadful vault rests a powerful sword imbued with the soul of the death deity's most fervent fanatic.

A deadly adventure for characters level 1-3 with a unique mechanic for handling player character death. An adventurer's final clumsy misstep or heroic sacrifice could ultimately save their trapped companions and themselves from a dismal end on the Windswept Island.
