In a retro-futuristic kingdom of jagged neon crystals, four magical guardians stand in a defensive formation. The Emerald Weaver (braided green hair, gem-encrusted tunic) uses her hands to pull glowing green energy from the ground. The Crimson Brawler (red hair, metallic breastplate) stands front-center with a defiant smirk, fists clenched. The Cobalt Engineer (blue skin, flight goggles) scans the horizon from a high crystal perch. The Amethyst Oracle (flowing purple robes, long wavy hair) floats slightly, casting a protective lilac barrier. The style is 90s heroic animation with sharp line art, cinematic lighting, and a landscape filled with towering translucent crystalline skyscrapers.
