Even Piell is a Lannik Jedi Master and High Council member, introduced in The Phantom Menace (1999) and played by Michaela Cottrell. The scar and the missing eye are the design's entire argument: this is a Council member who has been in fights, and both continuities write him as the chamber's hard-line voice.
His substantial story is the third-season Clone Wars arc set in the Citadel, the Separatist prison built to hold Jedi, where he is held with intelligence the Republic needs and dies during the escape. It is one of the few pieces of screen time any of the minor Masters gets that carries a plot rather than decorating one.
