Tall symmetrical tower, black void ...

Tall symmetrical tower, black void background. Top and bottom identical glowing orange rings (glowstone/magma block) with jagged crown-like spiky edges, dark orange base platform under each ring. Center: white/magenta glowing cube core with pixelated symmetrical pattern, two diagonal magenta beams crossing in an X through it, white particle sparks scattered around. Thin orange vertical pillars connect top ring to bottom ring along the edges. Sci-fi ancient temple / boss arena reactor vibe.
