I have a suggestion for QoL when it comes to change the edicts for High Elves and The Empire Fortress Gates. Special The Empire that has no defence edicts. Get rid of the ordinary edicts and add growth to the defence edicts. The High Elves have at least one defence edicts. Maybe each race shall have different perks. For example +/- corruption. And another thing, you must be allied to go through the Fortress Gates or INSTANT declaration of war! In other words; it should not be possible for a neutral / enemy to go through the gates.
Veni, vidi, vici
