Not really no.
This game is cannonically...3rd? I'm pretty sure.
The ending only gives the most vague hint...and more like expansion.
We have known for years Adol heads off to the North Pole in his 60s? 70s? for one last adventure.
The ending just gives extra ontext that it was due to Karja asking for his help regarding the Normans in some fashion.
But we still don't know much.
