Unreleased Netheril Time-Travel Finale Would Have Ended D&D 5e

An ambitious, unreleased finale that would have sent players back to the height of the Netherese Empire was once planned as a capstone for Dungeons & Dragons 5th Edition, but it never reached release. The plan would have used the mysterious black obelisks that have appeared across multiple 5e modules as connective tissue for a time-travel epic meant to serve as a dramatic send-off.

Design notes and an interview-based feature describe the obelisk thread beginning with Princes of the Apocalypse in 2015. Subsequent products kept dropping the obelisks as a recurring tease, and Rime of the Frostmaiden even includes a moment late in play where characters can activate an obelisk and travel back in time to Netheril’s height. Perkins said, “The original plan, in my mind, was that we would actually culminate the story by going back in time to fight the Netherese Empire.” Perkins added, “It was always on our radar to bring Netheril back in some way. And this was the way I envisioned it happening, because the only way you could really fight Netheril again is to travel back in time.”

The proposed finale was framed in the piece as an Avengers: Endgame scale event for D&D. The feature explained, “Instead of the boring sequence of fetch quests that is Vecna: Eve of Ruin, we could have gotten an epic time-travel adventure to give 5e a proper send-off. It could have been the equivalent of Avengers: Endgame for D&D. Imagine starting the adventure after Vecna won, and the heroes have to restore the timeline by traveling back to the age of Netheril.” More importantly, the feature noted, this would have been “the payoff for a mystery that had been tickling players’ imaginations since the first black obelisk appeared in Princes of the Apocalypse back in 2015.”

The concrete elements are familiar to DMs and players: black obelisks scattered through published adventures, Netheril as the ancient, spell-saturated civilization, and Vecna as the apocalyptic fulcrum that could justify a timeline-restoration campaign. Perkins said, “This was even teased at the end of Rime of the Frostmaiden, where players can activate the black obelisk and travel back in time to the height of the Netherese Empire. I always saw that as a shocking possible conclusion to the adventure, but I never imagined it was supposed to blossom into a whole project.”

The supplied material does not explain why the Netheril finale was left unreleased or whether its concepts survive in other projects. For players and Dungeon Masters, the takeaway is practical: the long-running obelisk motif was not a throwaway Easter egg but a deliberate narrative breadcrumb, and the Rime obelisk beat still offers a playable pivot into time-travel stakes. Expect community discussions and homebrew conversions to treat Netheril as an available endgame hook rather than a lost canonical finale.

What comes next is a living possibility rather than a published promise. The obelisks remain in published text and in session notes; DMs can choose to turn those teases into their own Netherese showdowns, and fans will continue to ask whether any future edition or release will attempt the kind of grand, time-bent send-off that was once imagined.
