The story:
The Phantasy Star Online series takes place on a fictional planet, Ragol and the desperate attempt by the people aboard the spaceship Pioneer II to colonize the planet. There are four different episodes in the story line, spanning a time of 21 years. (Note: Although it is titled Episode IV, it occurs chronologically prior to Episode III. Upon its creation, SEGA claimed that Episode III would be the final episode in Phantasy Star Online's story arcs. However, with the release of Blue Burst a year later, Episode IV was added)
