nordic portal 3d model

Create a futuristic Nordic teleportation gateway designed for a fantasy sci-fi game environment. The structure is a large stone archway portal built from ancient black obsidian stone mixed with sleek metallic Nordic technology. The arch is tall, imposing, and symmetrical, with thick carved stone pillars rising upward and connecting into a curved arch at the top. Deep Norse runes and Viking symbols are etched into the stone, glowing faintly with soft electric blue and gold light. Subtle cracks in the stone reveal glowing energy veins running through the structure, suggesting powerful ancient technology fused with mythological magic.
