Warning! Spoilers ahead for Guardians of the Galaxy #9 from Al Ewing and Juann Cabal
Star-Lord is back from the dead in Marvel Comics, having been reborn into an entirely different sort of character than fans may or may not be familiar with. After apparently dying in issues prior to the current Guardians of the Galaxy series from Al Ewing, Star-Lord is now back. However, he's lived an entire lifetime away from the Marvel Universe. During this time, his original origins have made a resurgence, seeing long-abandoned elements from his original conception making a quasi-return into his more modern ones (albeit somewhat remixed).
Star-Lord was created in 1976 by writer Steve Englehart and Steve Gan, making his first appearance in Marvel Preview #4. In his debut, Peter Quill was chosen to be the Star-Lord by a being known as the Master of the Sun, and his powers and motivations were supposed to have come from the motifs and themes seen in astrology. Englehart also intended to have Quill travel to different planets and have adventures that would be centered on the 12 different Zodiac signs, and it was only after visiting all twelve Zodiac houses that Peter would eventually become the Star-Lord. However, much of this was retconned and Quill's origins were revamped after this first appearance, as writer Chris Claremont took over writing Star-Lord by the time of his next appearance a few issues later.
However, it seems as though Ewing has brought some of these astrology concepts back into his explanation for Star-Lord's return in Guardians of the Galaxy #9. At the start of the issue, Peter is seen blowing up Olympus and the pantheon of Greek Gods as well. However, before the detonation, Quill's element gun recharges itself by siphoning the power of the gods themselves, which enrages them just before they were all believed to have been destroyed in the series' second issue. However, Peter Quill in fact survived, waking up in Morinus, a realm apart from the reality he knows. There he meets and befriends two allies who eventually become good companions. Having found no way to return to his own reality, Peter spends nearly 150 years in this realm (though apparently not aging as he normally would).
However, the gods are revealed to have survived as well, razing Mornius in their attempts to destroy Star-Lord and get their power back from his element gun. Running on pure and apparently magical instinct, Star-Lord does find a way back to his own reality, choosing to go back in the hopes that the gods will follow and Morinus will be spared. As Peter travels back to his own reality, he does hear a voice in his head, declaring him not just the chosen Star-Lord, but that he's also the Master of the Sun himself, and thus Master of the Solar System.
Throughout Peter's entire journey on Morinus, every page is labeled and signified as a different Zodiac house, such as the House of Beginnings, the House of Communications, the House of Death and Rebirth, and more, allowing Ewing to honor and reintegrate Englehart's original vision for the character in a pretty interesting and dynamic way.
While Peter does make it back to Earth and his own reality, it's right in front of Rocket Raccoon and Nova who are in the midst of facing down one of Knull the Symbiote God's dragons at the end of the issue. Unfortunately, this forces fans to have to wait and see how different this reborn Star-Lord might have become now that he's rejoined the Guardians of the Galaxy. It's possible Quill has become more powerful, becoming more like the original version of Star-Lord that was chosen by the Master of the Sun, now that Peter has become the Master of the Sun himself in Marvel Comics.
