Lava Pool

The tremendous stone doors slide apart to reveal a small cave, roughly square and about 30 feet on a side. Just inside, a jagged pit emits heat and a reddish glow, bathing the center of the room in a dim light. Beyond, a pair of strange dark obelisks are covered in handwriting, apparently scrawled in blood. While the sigils look like mere jibberish, it feels as though the stone itself pulses with a feeling of necrotic energy and foreboding dread.

Almost immediately, five figures materialize out of thin air. Four of them are dark wraiths, roughly humanoid in shape. The fifth is the pale specter of a young woman, similar in appearance to the one encountered earlier, but five or so years older.

If the party succeeded in correctly burying one or more suitors properly:

As one of the dark figures writhes, you think you make out the shape of a weapon you buried earlier.

On a successful Arcana or Religion Check to identify the obelisks (DC 20):

The obelisks are likely a phenomenon you’ve only read about before: “Sorrowstone”. Formed by great sorrow and empowered with the necrotic magic of the Shadowfell, it taps into the mind of nearby living creatures and manifests their most tragic memories and negative emotions into wraith-like embodiments.

Tactics

How each suitor behaves is directly related to whether their corpse was buried with its weapon and grave marker in accordance with The Main Puzzle.

If a suitor was properly buried, grave-marked, and armed, it will work to destroy the other suitors, attacking with Eternal Bloodlust against the nearest other suitor at every opportunity (regardless of whether that other suitor is likewise armed), and ignoring the players until all other suitors are killed. If only one such suitor remains, it will finally turn its attention to the players.

If a suitor was NOT properly buried and/or grave-marked and/or armed, it will work to defend Dahlia, the Westraven Witch. It will attempt to constantly position itself between Dahlia and the players, keeping her within its Eternal Protector aura where possible. It will defend itself from the attacks of other (properly buried) suitors if no other targets present themselves, but will otherwise choose the players first.

Dahlia, the Westraven Witch works exclusively against the players. She attacks from range with her Suffer as I Suffered attack, attempting to strangle as many players as possible simultaneously, and holding her Blood Curdling Cry for when one or more opponents finally reach her in melee. When she unleashes her Blood Curdling Cry, she will follow up with Haunting Look and Suffer as I Suffered attacks on anyone she successfully immobilized, in order to keep them helpless. Dahlia is aware of how the pillars work, and will attempt to lure or push players into them.

Dahlia and the suitor spirits are immune to the effects of the pillars.

Features of the Area

Lava pool: the surface of the lava is 10 feet below the level of the room. Anyone non-flying creature falling into the lava takes 5d6 points of fire damage. Any creature starting its turn there takes an additional 5d6 points of fire damage.

Pillars: the pillars are Sorrowstones (Dungeon Magazine 181). While each is triggered independently and has its own hit points, the limitation of a single Wisp Wraith being created per player still applies. The pillars ignore Dahlia and her suitors.
