The ruins were massive. The ancient dragons that had created this ruin were sure to be able to make the entire place accessible to the largest of dragons. Hut that was just how it should be. They didn't need to worry about the other races. They were the dragons that stood at the very top, they were more advanced and made their homes with many items that other races did not have.
The ancient dragons had access to the memory crystals that they stored their legacies within. They had the ability to be able to create statues and hide away secrets. They also had the power to make literal mountains. Overall, it was an amazing thing for anyone to be able to see.
When it came to the areas that midnight and Walker were exploring, they were just stunned by them. The stone carvings in the wall made with incredibly advanced understanding of earth elemental mana could make any artist unsure if they were capable of art in the least.
