Scene animated: rune ᚢ pulses with crimson light inside the glass sphere. Mana flows like molten lava around the stone. Orbiting crystals rotate and crackle. Light refracts through the glass, casting moving red patterns on the cave walls. Seamless loop. No camera movement. Only rune, mana, crystals, light refractions animated. No text, only ᚢ. --ar 16:9
