The concept of a trial tower was one that greatly intrigued the Black Dragon Avatar.
He had seen them, everyone had. But not many knew the trick to making them.
It wasn't a matter of a lack of power, demigods had more than enough power to do nearly whatever they wanted. The difference was in the knowledge. There was something missing in most people's knowledge, so even if they learned to read the language of the Ancients, they couldn't replicate their creations.
And, he didn't have the Runecrafting skill, so he couldn't do it that way.
He was assuming the second option was how they had done it here, as an actual Ancient loose in the Immortal worlds would have caused a much bigger uproar than his god sending him here to ensure that the hatchlings were not led astray by a follower of the World Dragon.
