Delicious in Dungeon

Laios and his small adventuring party — his stoic warrior sister Falin, the half-foot rogue Chilchuck, the elven mage Marcille — are wiped out by a dragon five floors into the local dungeon, and Falin is eaten alive on the way out. The survivors are flat broke. They cannot afford rations to attempt a rescue run. Laios proposes the only solution that fits the budget: cook and eat the dungeon's monsters on the way down. The series is the rescue mission and the running practical cookbook the party works out as they go, each recipe being also a working monster-biology lesson.
