Exiles in Elseworlds

This is a world much like others.  A world of heroes and villains.  A world where, shortly after the founding of the Avengers, the team found a hero from World War II, frozen in ice for 50 years.

Bucky Barnes.

Shortly after joining the team, his old foe Zemo -- the one who killed his old partner, Captain America -- kidnapped Rick Jones to lure Bucky to his death.  In the confrontation, Zemo drew a disintegrator ray and shot at Bucky, who dodged... and accidentally allowed the teenage Jones to be destroyed.  If he had his partner's indestructible shield, and had blocked that ray instead, who knows how things might have changed?

Without Jones, the being known as the Hulk devolved rapidly, until during the Secret Wars, the Beyonder separated the three minds within it into distinct beings -- and the savage Hulk unleashed on the world caused a split within the Avengers.  The West Coast organization reported directly to the Government, while the East Coast organization remained independent -- with further animosity caused by Bucky, now calling himself Patriot, and the new Captain America, John Walker.

With such a conservative new face for Captain America, the plight of the mutants went unheeded by the general populace, and though the Avengers aided the X-Men against the Sentinel Revolt, most mutants were killed, and the remainder went deep into hiding.

All these events are in the unclassified Avengers East file-logs, available to the Exiles here on the base.  Patriot has confirmed their status as extradimensional beings, and his own instinct assures him that Crusader, at least, is the offspring of Steve Rogers, trained in hand-to-hand combat by the original Captain America himself.

Here in the Avengers Mansion, they have access to beds, showers, good food, access to the media... and any other basic necessities they might require.
