The moment that Shakuni got the news that Ronan was back at the Avalonian palace he left his mountain and his sect and started a long and arduous journey towards Avalon.
He was the man who was the closest to sage-hood amongst all humanity , but he did not want to ascend before leaving a capable successor who could fill his shoes first.
For one hundred years he scoured the continent for a capable student for him to take in , however every single one of them dissapointed him to no ends.
His training regime that he wanted to teach was a brutal one , not many could sustain it. Hence even though he did reluctantly take students after five decades of dissapointment , none of the 10 that he took in could last in his training for more than 3 months time.
Finding it extremely painful and dangerous , most of them ran away , while one became mentally unstable as a result.
