Fantasy
Aincrad is a massive, floating steel castle, consisting of 100 interconnected floors
Author's Note: Aincrad is the iconic setting of Sword Art Online, a colossal, floating fortress suspended in the virtual sky. Shaped like an inverted cone, it features 100 expansive floors, each representing a unique world with its own landscapes, towns, forests, mountains, and dungeons. The floors are stacked like layers, with higher levels becoming progressively more challenging to navigate and conquer.
Each floor is connected by labyrinths, which players must traverse to locate and defeat powerful floor bosses to unlock access to the next level. The environment within Aincrad is immersive and diverse, ranging from tranquil villages and bustling cities to treacherous wildernesses and dark, monster-filled caverns.
What makes Aincrad particularly perilous is the death game imposed on its players. Once trapped in this virtual world, players are unable to log out, and dying in the game results in death in real life. This high-stakes environment amplifies the tension as players struggle to survive, form alliances, and strive to clear all 100 floors to escape the fortress and regain their freedom. Its combination of beauty, danger, and mystery makes Aincrad a striking and unforgettable setting.

Bites
Melee Weapon Attack: +2 to hit, reach 5 ft., one creature. Hit: 17 (5d6) piercing damage. If the target is Medium or smaller, it must succeed on a DC 10 Strength saving throw or be knocked prone. If the target is killed by this damage, it is absorbed into the mouther.
Blinding Spittle
The mouther spits a chemical glob at a point it can see within 15 feet of it. The glob explodes in a blinding flash of light on impact. Each creature within 5 feet of the flash must succeed on a DC 13 Dexterity saving throw or be blinded until the end of the mouther's next turn.
Multiattack
The gibbering mouther makes one bite attack and, if it can, uses its Blinding Spittle.
