So...between G3 and...G16,

There was another timing consistency, too...Owen commented that Lugh's deeds were from hundreds of years ago, though Tarlach only mentions it as "a few years a go" (in his book about Milletians, I think).

Then there's the problem of both Triona and Bella being Macha...Bella existed before Triona, but also existed after Triona dies in G3...that was a killer plot twist, but it's still kinda poorly narrated...
