A martial arts instructor who dubbed himself the "Dungeon Master" has been jailed indefinitely for sexually abusing four boys.
Nicholas Tuley, 43, of Preston in Lancashire, used the fantasy game Dungeons and Dragons to ingratiate himself to his victims.
He admitted 17 charges of sexual abuse at two earlier hearings.
Judge Heather Lloyd, sitting at Preston Crown Court, ordered him to serve a minimum term of 10-and-a-half years.
He will only be considered for parole after that time if he is no longer regarded as a risk to the public.
'Veneer of respectability'
Judge Lloyd told him: "You corrupted these children in the true sense of the word while all the time having the veneer of respectability."
Tuley admitted serious sexual offences against the boys and indecent assault from 1993 to 2007.
He preyed on his victims after meeting them while working as a martial arts instructor at Strettles Gym in Fylde Road, Preston.
Duncan Birrell, prosecuting, said the defendant used his martial arts prowess as a starting point for targeting his victims who did not see as unusual that he would physically take hold of them in a domineering role.
He added: "In addition to the Ju Jitsu he had other activities which he was instrumental in involving the youngsters at the club, such as Dungeons and Dragons and trampolining.
"The Crown say this offered an extensive opportunity to identify those likely to be most vulnerable and then ingratiate into their lives and sexually abuse them."
His victims were invited to his home to play a fantasy role-play game on his computer where each would imitate a character.
"Tuley was the Dungeon Master," said Mr Birrell.
"He was in control of the scenarios the children played."
He abused one boy after offering him personal tuition to help combat a violent stepfather.
Another was abused in the showers of the club.
Tuley was also placed on the sex offenders register and disqualified from working with children for life.
