// «Cristal mágico» · gpt-6-sol (medium)
// A cluster of magic crystals growing from a rough grey mossy rock: one tall central hexagonal crystal with a pointed tip, slightly tilted, and four or five smaller pointed crystals around it at different angles. The crystals are translucent-looking violet and cyan, lighter at the tips. The central crystal glows and floats a little above the rock.

// A rough, mossy stone nest for the floating crystal.
