Bladder-mines were a military technology first produced by Conjoiner Remontoire, after he received technical knowledge from Aura. Showing similar design elements to the hypometric weapon, hinting that the same species developed both technologies originally, the melon-sized bladder-mine functioned by "detonating" in a purple-black wave and warping space within a maximum spherical range of twenty kilometers. This resulted in the absolute destruction of anything within that space, even Inhibitor machines.

Remontoire theorized that the bladder-mine's underlying technology represented an early step in the Shrouder's mastery of metric-engineering, which allowed them to warp space around entire celestial objects (e.g., their Shrouds).
