The locations for my Requiem renders weren't picked at random. I tried to make them as lore-friendly as possible:
I don't think anyone paid attention to the backgrounds; Nevertheless, all of the renders where Requiem were having a time-out were picked from Avalon, the country they flew into to find The Sentinel Artifact.
The first one is an unnamed street from Dealership, a BO6 map multiplayer. The seaside looked more appealing, though unfortunately the sun was directly behind them which would make the lighting look awkward and unnatural.
The second location is a kiosk right next to the first location.
Even this one had a location from Avalon, too. An abandoned construction floor from Bounty, another BO6 multiplayer map. I headcanoned this as a small mission where Requiem went out to gather intel, but Strauss and Peck couldn't stop arguing.
Last but certainly not least is an apartment from the map Stakeout and you guessed it, it's from Avalon too.
Why Avalon? Because it's the only place where they stayed on for more than a day, uninterrupted by zombies, before traveling to Liberty Falls for their Reckoning.
I'm stretching the 3 days they spent in Avalon so thin because Requiem had little to no free time after prison so let me just have my headcanon renders, they're all I have left.
