|Location||North China Sea|
Lian Yu (Mandarin Chinese: 煉獄 Liànyù, translated as purgatory) is an island in the North China Sea where Oliver Queen was stranded for 5 years, between 2007 and 2012, before he was found by Chinese fishermen.
After shipwrecking on the island, Oliver buried his father on a hillside using several large stones. At first it seemed that Oliver was alone on the island, however, he soon learned that was not the case.
Flashbacks revealed that the island had been used by the Chinese government to banish prisoners, including the former General Yao Fei. It was then used by Edward Fyers and his mercenaries for an operation for an unknown employer. This plan involved launching a missile strike on a Chinese plane, in an effort to cause an international incident and damage the Chinese economy. For this plan, Fyers wanted to use Yao Fei as a scapegoat.
Two AIS agents were sent to free Yao Fei, but they were captured by Fyers as well. One of the agents, Slade Wilson, escaped with Yao Fei to the jungle, while the other agent, Billy Wintergreen, joined the Mercenaries.
Fyers then kidnapped Shado, Yao Fei's daughter, in an effort to force Yao Fei to continue working for him. Oliver joined Slade Wilson who trained him.
Slade and Oliver managed to clear an airfield and were about to capture a plane, but they missed their chance when Oliver came back for Yao Fei and was captured. Slade came back and saved Oliver, killing his former partner Bill Wintergreen in the process.
They then managed to free Shado. The three of them formed an alliance, as Shado trained Oliver in marksmanship.
The three of them ended up captured by Fyers and his mercenaries. And it turned out, Yao Fei had given them away after Fyers threatened to blow up the entire forest and kill them.
Yao Fei was forced to claim responsibility for the airstrike on a video. Fyers then shot and killed Yao Fei, leaving Oliver, Wilson, and Shado devastated.
They broke free from their bonds and began to fight and kill the mercenaries. Just in time, Oliver managed to change the direction of the missile aimed at the Chinese plane, and the missile landed on the camp, seemingly killing all the mercenaries.
Oliver found out Slade survived, but Fyers had Shado hostage. Fyers tried to negotiate, but Oliver used a bow and arrow to shoot him through his neck, killing him.
With no means to escape, the three of them were forced to stay on the island. Recovered from their wounds Shado and Slade continued to teach Oliver in combat, archery and Mandarin Chinese. They then were confronted by a small group of intruders who captured Shado, and their leader threatened her with a knife. Slade and Oliver took them out quckly, and Oliver brutally killed their leader with a stone. It was revealed a huge ship had landed on Lian Yu and they were looking for some mysterious graves.
The ship known as the Amazo began to launch explosives off on the island while looking for the ruins of the plane in which Shado was inspecting the dead bodies found in one of the graves. This alerted Oliver and Slade who raced back to find Shado only to be caught in the explosions causing Slade's hands to burn and Oliver to black out. Oliver was then transported to the ship and is kept prisoner by Dr. Anthony Ivo and his interrogator Sara Lance who survived the Queen's Gambit sinking.
In 2013 after the quake in Starling City, Oliver Queen had come back to Lian Yu and was living there again in the forests. John and Felicity came over and convinced him to return. The wreckage of a huge ship was spotted in front of the Island.
