An arch demon gate stands as a towering, asymmetrical structure carved from ancient, jagged obsidian and fused with corrupted, dark bronze. Its rough, almost molten surface reveals intricate, grotesque carvings of snarling faces and twisted limbs, glowing with an internal, hellish red light that pulses through its cracks. The massive, sharp archway appears cold and abrasive to the touch, framed by monstrous, fanged columns.
