When Does "Gargoyles: Dark Ages" (2023) Take Place?
"Gargoyles: Dark Ages" is a fantasy comic-book written by Greg Weisman that released July 12th, 2023. So when is "Dark Ages" set?
It takes place in the year:
We know this because during issue #3 "ALLIANCE" Chapter Three "The Oath" a character is crowned king and declares, "...and as high king, I, Kenneth-- second of that name-- do swear by Lia Fail, the Stone of Destiny--" "-- to protect Scotland and serve her people all of my days..." The real-world Scottish King Kenneth II became king in either 971 AD or 976 AD or 977 AD, according to different historical sources.

971 AD
We know this because during issue #3 "ALLIANCE" Chapter Three "The Oath" a character is crowned king and declares, "...and as high king, I, Kenneth-- second of that name-- do swear by Lia Fail, the Stone of Destiny--" "-- to protect Scotland and serve her people all of my days..." The real-world Scottish King Kenneth II became king in either 971 AD or 976 AD or 977 AD, according to different historical sources.
Furthermore, the main action of the first issue begins with time setting free-floating text that reads: "971".
Additionally, there is a prologue in issue #1 "ALLIANCE" Chapter One "The Reach" clearly labeled by free-floating text as "1997". (Since a character is remembering these earlier events, it is almost impossible for it to be 971 BC and 1997 BC.) So the entire story can be seen as a flashback from 'the present' of 1997 AD.
