To celebrate the 25th anniversary of The Sandman, Neil Gaiman looked back to the very beginning of the acclaimed series to answer a lingering question: What left the mighty Lord of Dreams so weakened that he was able to be imprisoned for 70 years?

“We learn, as the story goes on, that he arrived in England exhausted, dressed for war, from somewhere very far away, and that was why they captured him so easily," Gaiman told Fast Company ahead of the Wednesday debut of The Sandman: Overture, his six-issue collaboration with J.H. Williams III. "But I never told that story. And it’s big, and it’s very weird.”

However, over the course of the The Sandman's 75-issue run, there were at least two other untold tales that are certainly just as big, and undoubtedly just as weird -- and they both involve the letter D (naturally).

“If we ever get to the 50th anniversary, I may tell the story of how the character of Delight became Delirium, or the story of how the first Despair died," Gaiman teased. "But that’s the 50th anniversary, so there’s plenty of time.”

Although Destruction, who long ago abandoned his Endless duties and disappeared, was found during the series, Delight's transformation into Delirium was a mystery to which not even Destiny knew the answer. And while clues were dropped about the death of the original Despair -- she even appeared in 2003's Endless Nights -- readers were left wondering about the details, including who was behind it.

But, hey, we can hold out until 2038 for the answers, right?
