what is the lore for the new factions
Haven't thought of it much as I haven't focused on it yet, It may change in the future but it was derived from here,
"The misty hills of north-western Calradia are dominated by the Battanian clans, the original inhabitants of much of the continent. Their hilltop fortresses have born witness to countless wars fought to resist outside invaders"
for the Ancient battania, something like when the Battanians were driven out by empire and only left with the hill as their territory, some Battanians flee to the corner of the continent, they lost most of their men and so they establish a culture where women became independent (something like Amazons though I don't know much about Amazons) and they live there peacefully.
For the Valkyries
As I think Sturgians originates outside Calradia, from overseas, the valkyries were searching for their Sturgian kins, but they landed on the wrong side of the map, encountering the Ancient battanians and they were mistakenly identified as invaders so at the start of the game, they are enemies.
Those two faction came from my old mod which is Supreme Kingdom which also has a different lore, as they won't be compatible with this mod, I just insert them here.
