A gel-filled vat is a large container holding viscous fluid, often used for preservation, alchemical processing, or healing. Creatures or objects suspended within may be sustained, enhanced, or altered over time. Some vats stabilize magical energies, while others serve as containment for unstable experiments or regenerative treatments.
You see a massive glass cylinder, its surface slick with condensation. Inside, a thick, luminous gel suspends a shadowy form. Tiny bubbles drift lazily upward, the substance shifting sluggishly, refracting light in eerie, undulating patterns.
