Gulpo was born to Plo Koon's granddaughter, Win Lam. He inherited Force power from his great-grandfather, so he joined the Jedi. He became fast friends with Kit Fisto's great-grandson, Yelcha. After a year, he found that Jacen Solo himself was not Darth Caedus. "Darth Caedus" was actually a spirit that entered Jacen, and had been forced out of Jacen when he tried to warn Tenel Ka before Jaina killed him. Gulpo, Yelcha, and seven other Jedi vanquished Caedus, and shortly afterwards, Gulpo died mysteriously.
