GSS had also licensed preexisting virtual worlds from their competitors, so content that had already been created for games like Everquest and World of Warcraft was ported over to the OASIS, and copies of Norrath and Azeroth were added to the growing catalog of OASIS planets. Other virtual worlds soon followed suit, from the Metaverse to the Matrix. The Firefly universe was anchored in a sector adjacent to the Star Wars galaxy, with a detailed re-creation of the Star Trek universe in the sector adjacent to that. Users could now teleport back and forth between their favorite fictional worlds. Middle Earth. Vulcan. Pern. Arrakis. Magrathea. Discworld, Mid-World, Riverworld, Ringworld. Worlds upon worlds.
