Umm...

Except that Ruairi is older in Saga than he is in C1-C3, and Triona was alive in g2 but dead in G16. That has got to imply something about which generation happened first, right? Hint hint

In G1, Ruairi was a a wannabe paladin and Mari was still Mari, In G3, he was hanging out with Morgamt and Mari was Nao. The stories don't just reverence eachother slightly, they relate to eachother a lot and where they fit in the timeline is usually very clear.

By the time before G1 started, he had already quit and left to become an adventurer.

Also Tarlach's and Ruairi's reunion before Saga clearly happens after G16, since they mention about Triona and Lugh being dead.
