For Thanos' warship, see Sanctuary II

Sanctuary, also called Chitauri Space, is the name given to an asteroid field inhabited by the Chitauri. It was the domain of Thanos until 2018.


When Loki fell from Asgard and into Yggdrasil, he was transported to the Sanctuary. There, he was captured and tortured by the Other in order to ensure his compliance and submission; he was also trained by Thanos in the ways of mind control.[1]

Loki's adoptive mother, Frigga, used her powers to look throughout the universe in search of her lost son, and she found him in this sector of space, preparing to travel to Earth.[2]

Loki used the Tesseract to open a wormhole between Earth and Sanctuary, where the Chitauri were staged for invasion.

During the invasion, Iron Man flew a nuclear bomb through the wormhole into Chitauri Space, destroying the Chitauri Command Center and stopping the invasion before he fell back through to Earth.[1]

Thanos sends away Ronan the Accuser

After Gamora's betrayal, a furious Ronan the Accuser traveled to Sanctuary where he met with Thanos in person and angrily berated him for not taking Gamora's betrayal seriously. When The Other, Thanos' servant, scolded Ronan for disrespecting the warlord, Ronan angrily broke the Other's neck, killing him and forcing Thanos to speak to Ronan directly. Undaunted by Ronan's complaints, Thanos waved the Kree away, and while Gamora's betrayal was an issue, Thanos entrusted both Ronan and Nebula with fixing that problem. As Ronan departed, Thanos grimly warned him that if he returned empty handed again, he would "bathe the starways" in his blood.[3]

Following the end of the Infinity War, Thanos chose to not return to Sanctuary and instead teleported himself to Titan II, a planet named after the home he lost, where he intended to spend the rest of his life living peacefully on his farm.[4]


  • Thanos appears to have named his warship, the Sanctuary II, after this location which was his previous base of operations.
  • In the comics, the "Sanctuary", and its two duplicates, served as Thanos' space ark and base of operations in his plan of stellar genocide in an attempt to court Death. However, his plans were thwarted by the spirit of Adam Warlock, who turned the Titan into stone aboard one of Thanos' Sanctuary starships.
  • The coordinates for the Sanctuary are N5X2 1O6311411+2123518.
  • Tony Stark's vision caused by Scarlet Witch during the Attack on the HYDRA Research Base made him see his fellow Avengers dead on the landscape of Sanctuary.
