Dr. Chang was a respected archaeologist who worked for IPX and was an old friend of Anna Sheridan.[1]

He led the Icarus expedition on its mission to the newly discovered planet out on the Rim of known space, codenamed Alpha Omega III. He was killed by Dunne, a Psi Corps agent attached to the expedition, after most members of Chang's team were trapped by the Shadow artifact dubbed the 'Egg.'[2][3]
