Behold the victory of the Empress, approx day 400.
There is basically no opposition to her now - I started as Vlandia and was loyal to it for a very long time against the odds, but in the end I just couldn't stop the steamroll. Vlandia had 4k strength vs the Empire's 12k, and there was simply no meaningful way to oppose them - so I flipped factions.
Now, only 3 factions really exist - Aserai, Western Empire, and Southern Empire. It's just a question of when the southern decides to eat them both - they're on borrowed time. Nothing can be done for them, they're hopelessly outmatched.
Some sort of internal clan strife mechanic needs to be introduced, I think.
