The Sentry Tower
A stark stone tower rising thirty feet above the cobbled streets. It features a narrow interior chamber with a prominent stone mantelpiece and a cramped upper ledge. The top is crowned with a parapet and narrow battlements that provide a commanding view of the surrounding City of Glass. Currently, the structure is a scene of absolute chaos: makeshift barricades of crates block the walkways, and the very masonry ripples and shimmers as if the tower is losing its grip on physical reality.

The Sentry Tower
The air is thick with the scent of ozone and the terrifying psychic weight of a mind flayer presence. The environment feels claustrophobic and unstable, punctuated by the blinding flashes of wild magic and the jarring sensation of the floor occasionally turning as fluid as water.

History
Tactical Hazards
The cramped quarters of the parapet mean that any forced movement, such as a shove or a psychic blast, is likely to send a combatant over the edge. The makeshift barricades provide half-cover but restrict movement, turning the rooftop into a deadly bottleneck where magic area-of-effect spells are particularly devastating.
Planar Instability Effects
During combat, the stone may become insubstantial. On certain turns, creatures must treat the floor as difficult terrain as they partially sink into the 'watery' stone. In extreme cases, attackers find their weapons passing through walls without dealing damage, or they may sense they are falling through the floor for a brief, terrifying heartbeat before reality snaps back.
The Defensive Mantelpiece
The interior mantelpiece is more than a decorative feature: it serves as a secondary elevated firing position within the main chamber. It is currently being used by defenders to gain height against assassins who teleport into the lower levels, providing a small measure of safety in an otherwise exposed room.

Rumors & Plot Hooks
- 1.The tower is built upon a thinning spot between planes, which is why it glitches more than the surrounding buildings.
- 2.There is a hidden cache of glass-steel weapons buried beneath the stone mantelpiece.
- 3.Anyone who falls from the tower during a ripple event might not hit the ground, but instead fall into another realm entirely.
Classified Entry
The tower's glitching is not just a side effect of the bombardment: the structure contains an experimental 'Anchor Stone' in its foundation that is failing, threatening to blink the entire building out of existence.
