Interesting idea. Yes, some religious descendant might actually do this. Even though this is gamey approach, I don't want for such a great dynasty with such a capable leader to simply steal Byz crown. Empire of Diocela/Duklja sounds much better, and then yes, I guess mending this "split of Christianity" could be valid RP decision.
Mihajlo was working on eastern alliances. Moesia already joined since the relationship event fired. Old and now incapable, but with strong army, Strategos of Samos received two Dukljanins as the wards, but as soon as he signed alliance those wards were recalled. He is now pissed, but he is over 60 and incapable... and still an ally. Armenicon and Paphlagonia joined the league with much less fuss.
And I gotta give it to my chancellor:
I guess it is only fair to eventually press his claims. Problem is, one French count and one HRE count are already grabbing his brother's lands. Oh well...
Singidunum became part of the realm but is ruled by some Greek guy. We can't have that in our Serbian de jure lands. So as soon as cooldown is finished, chancellor will move to Singidunum since Mihajlo is not willing to cause more tyranny. And then, after allies caught some breath, but not too much so they don't start some silly wars on their own, it was time for Naissos and holy war for Salerno. Mercs were already arriving at Naissos before war has been declared.
As you can see, there is a revolt in Hungary. I know my grandson will eventually have a claim to Hungarian throne.... but why waiting and leaving things to chance. Revolt is for independence of the Tengri rulers. I guess Hungarian king didn't holly warred Wallachia but liberated it instead. Hungary is allied with HRE and Denmark, but that won't apply when attackin grebels, only Hungarian king himself will be hostile. Anyway, I think of moving in.
Meanwhile, king Mihajlo acquired another siege commander. Brother of count of Seleukia wasn't exactly liking his brother too much. He arrived with wife and the kid, which is not great since court count is already above 50, but still, siege commander is always welcome.
And once few allies arrived at Naissos, impatient Mihajlo sent order to his commanders to assault the citadel (lvl1 walls and fortifications) and the city and to move to Turnu. Siege and movement commanders were swapping as the leaders of the center. Few days before arriving to Turnu, Naissos signed surrender and holy war against rebels was declared. Rebels were doing some country-side tourism in Severin.
But as soon as army arrived in Turnu, scouts reported that Hungarian king was already laying siege to Tirgoviste for some time. We can't allow for rebels to have any reason to think they should abandon their revolt. So army immediately proceeded to Tirgovise, had some fun with Hungarians and continued their siege which was already near finish. Afterwards city and temple holdings were stormed as both had laughable walls and fortification.
At this point, rebels have won siege of Severin, ensuring that warscore against Hungary is in their favor, so Duklja army was now eager to play with them too and speed up this war. Then army moved into Turnu where allies already started the siege. This actually caused some allies to move to Galaz. If you mix impatient king with lvl1 defenses, you will get orders of assaulting as result. Army proceed to Galaz where allies were already finishing of remnants of Hungarian and their allies.
But army wasn't going for Galaz and warscore with rebels was already 100%. Khagan of Pecheng had less than 400 soldiers and two Hungarian counts were attacking him. One was count of Turnu and he already got Khagan's capitol, but since that was about to be conquered, that war will be ended. So into Pecheng lands, holly war of Wallachia was won (which got me a solid commander, Vlach Orthodox) and new war for Moldau is declared.
Some allies moved into capitol Birlad, now liberated, while main army attacked poor Pechengs and had some more assaulting to do. Then I spotted this:
That idiot of my genius son arranged a marriage with my vassal, that inherited Apulia after mysterious death of my in-the-way grandson. What possible benefit would be gained, let alone some proper claim? I guess he deserves his lunatic trait. Mihajlo immediately starts plotting death of the poor innocent girl... who should have known better herself than to try becoming a queen.
Which reminds me: ex-ruler of Naissos was already taken care of. He arrived at my court, which I don't understand, but whatever. He is Bulgarian and I get there are no other Bulgarian rulers around, but I guess he could go to some of my few vassals. Anyway, I started plotting against him. Then his infant son inherited his 100 coins and then he will be put to some use eventually. After conquering Wallachia, one city was given to young Bulgarian noble, and one to my renounced possessed son, the only son Mihajlo managed to father with his genius lowborn girl. Well, if he was able of conjuring his personal witch at the age of 1, I don't wanna wait until he is 20, conjuring some dragons and starting his own Blackfire rebellion. So instead, he got one city to play with.
Naissos was not given to Dukljanin member, but there was some Serbian guy in my court, for years now with dynasty of his own. So why not - he was married to some lowborn fertile Serbian girl and given Naissos. Just to be clear, fertile woman means either lustful or "Midas Touched"/"Gray Eminence", or combination of the two.
