D: Before Merlin was a soothsayer he was a miraculous child who solved the mystery of Vortigern’s Tower.
W: What mystery was that?
D: Every time the tower was raised by Vortigern the hill on which it was built swallowed the tower whole.
W: And the answer to that mystery?
D: The answer to the mystery was that the hill was hollow…
and in the hollow of the hill was a pool…
and in the pool two stones languished…
and in each of the stones was a dragon struggling to get out.
One Dragon was White, and the other Dragon was Red.
W: And what was done to reveal this mystery?
D: The Hill was excavated…
The pool was drained…
The stones were pulverised… and the Dragons loosed.
W: What happened then?
D: The Dragons contended… and became One.
W: Thus, the braided tower was raised upon the hill… and remained.
