NORTH BEND — The legend of King Arthur is a complicated thing.

Written in incremental tales by dozens of authors over hundreds of years, there isn’t a definitive storyline of Arthur’s life — just lots of little pieces with overlapping characters who often play different roles depending on the source.

That’s what North Bend director Michael Gonzalez found when he set out to find a King Arthur play to stage with On Broadway Thespians. None of the existing scripts offered the comprehensive story he wanted, and all left out more than he could accept.

So he decided to write his own version of the legend: “King Arthur and the Lords of Avalon,” which premieres Friday, Aug. 8, at Pony Village Mall in North Bend, in the space across from Sears.
