There was the same influx of mana that had happened when the tower had folded itself in to a book. Walker was still not sure if it had been real until this second. The book opened up and unfolded over and over making runes appear in the air. The runes were shaped the same way that the tower was building itself. However, it had changed in appearance.
Instead of the sandstone yellow and greys that had been over the walls, there was a black and green stonework building with many runes covering it. The seems were so perfectly fitted that Walker couldn't tell how the stones were put together, yet he could tell that it had been handcrafted and not done with magic. He just had a feeling.
The rune designs were radically different than what he had seen before. Not only were they different from the runes that he had seen before he had been to the ruined desert city, but they were more advanced than what the desert elves had carved over them.
