Since, I am doing a modmod of Orbis,
If I remember right, Orbis was also a modmod for FfH2. If the 3K mod's hero system belonged anywhere else, it would here. The heroes for FfH2 should have been more involved that just as one-unit wonders.
As for Orbis, I hope you do well with it. The AI seemed way too easy to beat and seemed to declare war even when they didnt have the units to really wage it. Think had to do with the combined power of all their armies, but hundreds of strength 3 archers wont do much against an SoD of str 8 items with siege equipment and spells.
I'll keep an eye out for it and good luck!
