Dungeon Floor Plan (The Sunken Chapel)

Prompt: tabletop RPG battlemap grid layout of an ancient flooded underground complex called "The Sunken Chapel" (A Capela Afundada). Vintage dungeon blueprint style on parchment paper. The layout contains 10 connected chambers with submerged stone corridors: Room 1: Entrance Chamber (flooded stairs leading from a cellar hatch); Room 2: Sunken Corridor (narrow slick stone hallway); Room 3: Hall of Pillars (cracked stone columns with murky knee-deep water and patrolling zombies); Room 4: Side Chamber (small dead-end alcove with old skeleton under a fallen pillar); Room 5: Vertical Shaft (dry well shaft with hanging ropes); Room 6: Flooded Gallery (deep waist-high dark water); Room 7: Sunken Chapel (sacred hall with overturned stone pews, cracked altar, and faded stained glass); Room 8: Corridor of Seals (walls covered in ancient protective magical runes); Room 9: Sealed Vault / Chest Chamber (large ancient bronze door, a large Coral and Shell Guardian statue standing in front of a dark bronze chest); Room 10: Treasure Niche & Alternative Exit (small dry alcove with a secret ladder going up). Clear room numbering, dark fantasy aesthetics, grid lines, clean cartography line art. --ar
