WARNING: This article contains spoilers for Avengers #8 by Jason Aaron, David Marquez, Justin Ponsor and VC’s Cory Petit, on sale now.
Two of the higher profile superhero teams in the Marvel Universe are the Avengers and Guardians of the Galaxy. If you narrow your focus to just the Marvel Cinematic Universe, Earth's Mightiest Heroes and the Guardians are the only superhero teams a majority of fans are familiar with.
The Avengers have used a number of different facilities as its headquarters, from Avengers Mansion to Avengers Tower. As for the Guardians of the Galaxy, they primarily stick to their Milano spaceship while also frequenting the floating, severed Celestial head called Knowhere. The Celestial that Knowhere used to rest atop of was killed many millennia ago, with aliens deciding to harvest the head for resources before turning it into a pitstop for lowlifes and space pirates.
Celestials were the focus of Jason Aaron, Ed McGuinness and Paco Medina's opening arc of Avengers as the Final Host returned to Earth to wipe it out of existence. Many of Earth's heroes assembled to repel the attack, with a group of Celestials deciding to leave Earth a gift in the form of the Progenitor, the very first Celestial to venture to the planet back in 1,000,000 BC. The cosmic giant was killed and buried in the ground by the prehistoric Avengers, but now the carcass has been lifted out the ground as a beacon of hope and life at the North Pole.
The Avengers team has decided to make the Progenitor its new headquarters, naming it Avengers Mountain. Black Panther has the best architects in Wakanda working with Captain Marvel's Alpha Flight to make its insides inhabitable, turning the spine into a spinal tap elevator, along with turning ventricles and cavities into livable rooms, etc.
What we see with Avengers Mountain is a mirror of what happened with Knowhere in space. In both cases, a dead Celestial was mined and turned into a resource facility for characters in the Marvel Universe. But instead of the Guardians of the Galaxy visiting Knowhere, the Avengers have called their Celestial home.
