A circular emblem made of worn brass and obsidian, featuring a stylized open book at the center with glowing circuitry lines etched into its pages. The emblem is surrounded by ancient script carved into the outer ring and small embedded crystal nodes at the cardinal points. The surface is slightly weathered with deep engravings and raised details, giving it an arcane technological feel. Designed with perfect radial symmetry, for 3D printing or game asset use.,
