Same scene animated: the rune ᚠ pulses with golden light like a heartbeat. Floating crystals slowly rotate, sending out golden sparkles. Mana streams flow upward from the cave floor continuously like living fountains. Golden droplets fall from stalactites like mana honey. Seamless loop. No camera movement. Only the rune, crystals, mana streams, and droplets are animated. No text, only the runic symbol ᚠ. --ar 16:9
