Your body can alter its outline without changing its essential mass. You can pass through an opening as narrow as 1 inch when not carrying or wearing anything you cannot reasonably compress. You cannot use this trait to pass through a sealed barrier or to carry another creature through the opening.
You can remain without breathing, and you have advantage on ability checks and saving throws you make to avoid or end the Grappled condition. You still need food and water, and this trait grants no resistance to damage.
If you remain motionless against a smooth, similarly colored surface, your translucent body is difficult to distinguish from it. You have advantage on Dexterity (Stealth) checks made to hide in this way. This trait does not make you invisible, and obvious movement or carried gear can give away your position.

Cube-born folk tend toward Constitution and Wisdom, shaped by endurance and careful perception; assign ability score increases according to your character creation rules, with no fixed bonuses.
Their bodies hold a faint pearl sheen and register vibrations over a wide area.
Pearl Veils commonly inhabit flooded caverns and old cisterns. Their communities are known for careful listening, oral history, and guiding travelers through submerged passages.
You are a thinking, speaking descendant of the dungeon's most patient scavenger: a clear-bodied cube that remembers every corridor it has crossed. Your people prize careful observation, mutual boundaries, and the stories carried in ordinary things. To strangers, your calm stillness can seem unsettling. To you, adventuring is a way to see what lies beyond the next doorway, and to prove that a body born in a ruin can choose its own purpose.
Cube-born are intelligent descendants of dungeon-dwelling gelatinous organisms.
Their translucent bodies hold a firm, deliberate outline, usually a cube with softened edges, though they can round their corners or stretch slightly to express themselves. A network of denser gel, colored inclusions, and suspended mineral grains forms their sensory core. They perceive pressure, vibration, chemical traces, and light, then communicate through rippling patterns, scent, and speech. Clothing is worn for modesty, social custom, and carrying tools, often secured by wide bands that do not constrict their bodies.
Caves, old dungeons, damp cellars, abandoned mines, and carefully maintained communal pools.
Cube-born communities favor places with mineral-rich water and several safe routes to the surface.
A young cube learns to control its outline and movement, usually under the patient attention of several elders.
The cube can travel independently, take on a chosen shape, and participate fully in communal life.
The cube's memories grow unusually deep, and its body may develop slow-moving swirls of mineral color.
Cube-born communities are often organized around shared pools and remembered routes.
Knowledge is passed through spoken accounts, scent-markers, and small objects kept in communal chambers. Young are usually cared for by several adults, and personal identity is considered a chosen shape rather than a fixed one. Most cube-born develop a customary outline that helps others recognize them, but changing it is ordinary and carries no implication of deception. Their etiquette places unusual emphasis on consent: sudden contact, blocked passages, and unexplained stillness can all cause alarm.
Cube-born traditions honor cycles of renewal, the patience of stone, and the preservation of memory.
Some revere gods of knowledge, caves, healing, or safe passage; others keep no formal faith and treat remembrance itself as sacred. Their societies favor cooperation and clear agreements, but individuals may follow any alignment.
Many people first mistake cube-born for mindless dungeon hazards, so trust often begins with a spoken greeting and a clearly visible pause.
Cube-born tend to respect cultures that state boundaries plainly, and they are wary of anyone who treats living bodies as property or raw material. They can form deep attachments across species, though their long lives and unusual senses sometimes make those bonds difficult to explain.
Their refuges are shaped around broad, shallow basins, smooth ramps, and alcoves that provide privacy without trapping anyone.
Rooms often have rounded corners and little loose debris. Aboveground cube-born commonly adapt bathhouses, cisterns, and courtyards, using screens and shallow pools to create familiar spaces.
