Cistern Warden

The Cistern Warden was once a man responsible for the floodgates and drainage tunnels beneath Velkarth. Long exposure to the damp darkness and the distant echo of the Song below the city has twisted him—body first, mind slowly after.

His frame is unnaturally elongated, as though stretched over time. His arms hang too long for his torso, fingers thin and tipped with dirty, overgrown nails. His neck extends slightly farther than it should, allowing his head to tilt at unsettling angles. Sparse strands of long, gray hair cling to his pallid, sagging skin, often plastered against his face by moisture. His teeth are human—but broken, chipped, and uneven. The fractured edges give them a jagged appearance, as though sharpened by accident rather than design. He moves with disturbing control: sometimes hunched and crawling along stone and wall alike, sometimes rising to full height with slow, deliberate intent. He listens often—head tilted, neck extended—as though hearing something beneath the hearing of others.

The Warden is not mindless. He understands speech and simple strategy, but his reasoning no longer follows human patterns. He perceives intrusion, noise, and disruption. Those who descend too far into the tunnels are marked as disturbances to be removed. He does not guard the depths out of loyalty. He guards them because without the depths, he no longer knows what he is.

Some say he still remembers his name. He simply refuses to answer to it.

Lair: The Lower Cisterns of Velkarth

The Cistern Warden inhabits the flooded maintenance tunnels and stone reservoirs beneath Velkarth. Once part of the city’s drainage system, these chambers are now cracked, unstable, and partially submerged. The air is damp and heavy. Sound echoes unpredictably through narrow corridors and open cistern halls. Dim light reflects off black water pooling between broken walkways and rusted floodgates.

The lair consists of:

• Flooded stone floors and shifting water levels

• Narrow bridges and maintenance platforms

• Cracked support columns and exposed pipework

• Vertical shafts and climbable walls

• Pervasive dim light and deep shadow

 Within these tunnels, the Warden moves with unnatural ease, using walls, ceilings, and waterlogged passages to isolate and ambush intruders.

Lair Actions

On initiative count 20 (losing ties), the Cistern Warden takes one of the following lair actions:

• Rising Surge. Water bursts through cracks in the stone. A 20-foot square area the Warden can see becomes difficult terrain until initiative count 20 on the next round. Creatures in that area must succeed on a DC 14 Strength saving throw or fall prone.

•  Extinguish the Light. Moisture and pressure snuff out illumination. One nonmagical light source within 60 feet is extinguished. Magical light of 2nd level or lower within 60 feet has its bright light radius halved until initiative count 20 on the next round.
  
  
• Echoing Pressure. The stone resonates with a distorted echo. Up to three creatures of the Warden’s choice within 60 feet must succeed on a DC 14 Wisdom saving throw or be unable to take reactions until initiative count 20 on the next round.
