In the Original Trilogy, Allanon always says that he is the last Druid. In the end, before he dies, he seals Paranor to block entry to the evil creatures seeking to use artifacts contained there to do more harm.

But before dying, Allanon transfers some of his powers to

Brin Ohmsford (a promise and an oath that her offspring will restore the order)

and

Rone Leah (the power of Hadeshorn enhanhing the Sword Of Leah).

Why did he not train his descendants himself, As Bremen taught him? Did he believe that magic will end? Or were there no suitable candidates?
