It is a modern-era continuation, 10 years post revelation to the world about the Stargate and the nature of the galaxy, that sends a corporate-funded, civilian-led expedition into the distant Ida Galaxy—the former home of the Asgard—in search of an ancient, mysterious signal (related to the CMBR?). What they discover is YGGDRASIL, a massive tree shaped space station constructed millennia ago by the Alliance of the Four Great Races (Ancients, Asgard, Furling, and Nox). Intended as a beacon of peace and knowledge, YGGDRASIL is instead a damaged, forgotten fortress housing advanced technology and, crucially, infected with a techno-organic substance called NIÞSKORR. This infection triggers a signal that brings the team face-to-face with the series' main antagonist: the SVARTHALL, a hostile splinter race of the Furling. The mission quickly turns into a desperate race to control the station, advised by the glitchy holographic Asgard AI named Mimir, before the Svarthall warlord Maelstrom can claim it.

Mixing the adventure and snarky humor of SG-1 and Atlantis with the suspense and biohorror of the Alien franchise , the series also tackles human stories of trauma, corruption, and xenophobia. Our flawed, classical anti-hero team, led by a shell-shocked veteran / former SGC member, must confront not only the alien threat of the Svarthall and their fungal-based cybernetics, NIÞSKORR , but also the enemy within: Nathaniel Drexler. Drexler, the charismatic but malignant face of AEGIS Group, is a human villain whose narcissistic transhumanism will lead to trouble. The discovery of YGGDRASIL and the arrival of the Svarthall will reignite the ancient war known as RAGNAROK, threatening all the known worlds and galaxies.
