I mean no offense. I'm one, too, just not of the following era.
The shows Vikings and The Last Kingdom:
Vikings started in what... 793? The Last Kingdom starts in 866? There appears to be a lot of overlap in the names (I've only just started episode 1 of TLK, but have watched all of Vikings so far).
So can someone help me sort out exactly what overlap there is? Which one (or both?) of these stories is playing fast and loose with the timeline? Is it (as far as the Saxons are concerned judging from what I've seen so far) the same story as Vikings?
In the immortal words of Timon: "WHAT'S GOING ON HERE!??!!?"
