I may have some scouts coverage holes, but that is really some poor propaganda
Every person with at least some intel and basic math abilities can locate game leaders. And Fomoria does not belong there.
It's obvious that on top we have Ermor [biggest nation in the game, best location], Marverni [MOST of artifacts, including the most powerful ones like forge hammer, chalice, sceptre], great national mages and good diversification already. I'd say Helheim would be 3rd position, but his premature attack counts as a resignation from that spot.
It's obvious for everyone that Helheim is only helping Marverni and Ermor. He knows he cannot win the war - it's also not certain if he can lose it. So the right question is - why is he helping 2 other powers? It's after all Helheim that attacked Fomoria, not the other way around.
So maybe we should start checking who has most provinces? Who has best research? Most gem income? And above all - who has most VPs? But I doubt those are answers that would make Ermor happy
