Oliver Queen's past is getting darker.
The organization Shadowspire is growing. Ryan Robbins has joined Arrow Season 4 as Conklin, a sadistic and ruthless member of the group that will plague Oliver in flashbacks. The role is recurring.
Jimmy Akingbola was earlier cast as the leader of Shadowspire, Baron Reiter, who in the comics was known as Baron Blitzkrieg, but may not be appearing as such on Arrow.
Robbins joins other new characters coming to Arrow such as Neal McDonough as Damien Darhk, Echo Kellum as Mr. Terrific and Jeri Ryan as Jessica Danforth.
