Dougal decisively lights a flask of oil and cleanses the ghoul nesting area with flame. It might be hard for the newcomers to understand his impulsive actions, but Dougal has seen first-hand the evils of ghoulism. If Dougal can do his part to eradicate the plague of undeadism from the dungeon, then he does not hesitate to act.
The ghouls' bedding material burns for 1 turn with a cheery glow. There is no escape for the writhing creepy-crawlies as they meet their maker. When the fire seems to be dying down, there is a sudden burst of flame, as though something flammable has caused a secondary fire, then at the end of the 2nd turn, those flames die down too.
Will Dame Simonetta use this opportunity to do any self-care? She's been through a tough fight and got hit the face. Is she vain about her appearance? Does she have any kind of ritual to put herself back together? Just trying to get a read on her character: Does she maintain a noble appearance in the face of adversity, or is she covered in dungeon muck like everyone else?
Our heroes sift the ashes and collect 750 gold pieces! There are 20 coins to a pound, large sacks hold 600 coins, and small sacks hold 100 coins, I believe. Please let your DM know how you bundle up the treasure for transportation. One option you might consider is to cache the gold for future retrieval on your way out of the dungeon.
Additionally our heroes find a silver and moonstone necklace. The finer details of the craftsmanship were damaged by the heat, and now it is only worth 130gp, still a worthwhile haul. Last but not least our heroes find a broken lantern. The glass is completely shattered and it's quite useless. The lantern was full of oil, which accounts for the secondary fire.
Noh inspects the alcove with his druid's senses and gives the verdict: No lice, ticks, roaches, or bedbugs could have survived the inferno. The ashes will nourish new substrate and bolster the cave ecosystem. In a year's time this area will be thriving with fungi, insects, invertebrates, and other healthy subterranean life. Who knows: It might make a comfy new home for dungeon megafauna like a giant lizard or spider-goat.
Our heroes feel a sense of satisfaction, that by destroying the ghouls and their lair, they have contributed to the dungeon upkeep and done their small part for future generations. What next, friends? Your DM suggests up, down, and south are your options, with the south tunnel your safest bet.
OOC: Due to the fire and smoke, I gave +1 chance of wandering monsters, but our heroes lucked out: no encounter.
