"We journeyed to northern Norway to see if we might 'see the heavens lift up her dark skirts and flash her dazzling privates across [our] unworthy irises' And she did," Lourd wrote. "I love you times infinity."
Fisher was 60 years old when she died last December, just a few days after she was rushed to the hospital after suffering cardiac arrest on a transatlantic flight. About six months later, the Los Angeles County Coroner's Office cited sleep apnea as a cause of death and listed drugs that were in her system at the time of her death. It was unclear whether the drugs, which included cocaine, methadone, ethanol and opiates, played a role in her death.
Many others, including Fisher's "Star Wars" co-star Mark Hamill, also took to social media to remember her.
"No one's ever really gone... #AlwaysWithUs #CarrieOnForever," he tweeted.
