Opal is particularly notable for several aspects of its depiction in the second Starman series. The original settlement, "Port o' Souls", was established by Puritan settler in the early 1700's. In 1884, the town elected Brian "Scalphunter" Savage as sheriff; Scalphunter is later reincarnated as Matt O'Dare , and later as Star Boy. About the same time the morally ambiguous Shade made Opal City his home.
The modern Opal City had its greatest expansion in the 1910s to 1930s, as evidenced by its many Art Deco buildings. An interesting detail is that the city, from its foundations, was heavily tainted with dark magic, first due to the activities of an unholy cult calling themselves the Tuesday Club, which was comprised of Opal's most influential and powerful citizens, from its beginnings as Port O'Souls in the Elizabethan era until Savage killed almost the entire cult the final night of 1899. Savage was killed by the last surviving member, but this man was killed seconds later by Savage's assistant, Carny O'Dare. Little after the foundation of Port O'Souls came the curse of the Black Pirate, binding all souls that ever died in Opal to the earthly plane. The pinnacle of this was Hawksmoor St. John, the architect who planned Opal's great expansion, also a fervent Satanist, who christened several buildings in blood so the lines drawn between them formed a perfect five-pointed star. In the WWII years, a group of Nazi occultists planned to drown Opal into a void dimension, but the ritual was partly stopped by Etrigan and the then Starman Theodore Knight. However, the aftermath of all of this was an atmosphere tremendously saturated in magical power, which Simon Culp sought to use in conjunction with his own augmented power to allow the Nazi ritual to be completed, to destroy what his archenemy Richard Swift, the Shade, loved most. However, Culp was defeated and the souls liberated from the Pirate's curse.
It was in 1939 that the first Starman Ted Knight began his career as a superhero. Opal itself at one point in its history suffered very heavy damage, first by explosions leveling several large stores, courtesy of the Infernal Doctor Pip, and later, due to the same man, demolition bombs designed to destroy much larger sections of the city during Culp's attempted destruction of Opal. Additionally, the Post Office/Government building was torn out of its foundations and taken into space by Ted Knight, to protect the city from a nuclear bomb planted deep within it by the Mist. The bomb safely exploded in outer space, and the reconstruction of Opal started.
Though not specified, consumption of Absinthe may still be legal within Opal City even though it was banned in the United States in 1912.
