Tempest

Tempest is a covert organization responsible for sabotaging the Queen's Gambit in 2007, resulting in the death of Sara Lance, Robert Queen, and the captain of the yacht. It's also what led Oliver Queen to be stranded on Lian Yu while awaiting rescue.

According to Moira explains that Tempest was created to fix the Glades and cure the city. Oliver later learned that their logo was an outline of the subway lines connected/leading to the Glades.
