Actually what Zakky say is right. And Fleugs.
Speaking from one of the realms that interact with Perdan whether through wars, or peace before the storm, Nivemus.
One word I have for Perdan army: Respect. Their movements are impressive, their nobles are working hard. PMW army. Only those opposing military leaders who face them will know what this army did and continue to do.
Taking Perdan army aside, about the reason for war: Perdan has won the war with Eponllyn. The war was first started with intention to acquire Eponllyn lands passage right for themselves to travel to north. Nothing was mentioned about taking lands from Eponllyn; I think there is where Vita come in and states many times about the reason for war. What many Eponllyn nobles dislike is the fact Perdan taking the lands. However we need understand that if you have some other realm namesake city, what to stop them from coming after your realm in future? Reminded me of when Fontan asked for Fontan city back from Caligus realm but Caligus Ruler Dobromir refused to give back. And Caligus had army power to back up his word at that time while Fontan not, for Fontan was at its weakest moment at that time.
Even as Eponllyn ally, Nivemus army entered the war a bit too late, let face the reality. Eponllyn allies do not act in time. Eponllyn already under severe pressure from both Perdan and Vix armies; hence my term coinage "one moving in and another moving out". Another Eponllyn ally, Sirion was busy occupied with war against Oligarch and did not come. Another Eponllyn ally, Fallangard now is facing reality or consequence whichever you wish to call it, for not helping Eponllyn. Now Fallangard know who will come to its aid against Vix and Perdan and even Caligus. So I understand Vita phrase previously about "they come for me but you no come help me" kind of quote. I think I listen to this quote somewhere before.
About Vix, I have 1 word for them: Follower. They appear to follow whatever Perdan decides and does. Perdan war with Eponllyn? Well, Vix also followed Perdan. Perdan taking Eponllyn lands? Well, Vix also followed Perdan. Make many players including myself think that perhaps the little war between Perdan and Vix are just civil war for show.
The fact that they took the land, by itself, has little to do with why people are angry with Perdan's players. Oh, and I seem to remember a certain army with insanely good movement times in Perdan. A certain Perdan Lions? That in itself has me very unwilling to give Perdan much respect in regards to army ability. Especially the older players.
