Hopefully you'll still see this.

Ibevar is a bit weird. You start off with a lot of strengths, but a lot of problems too. You have elven administration, really nice national ideas for military expansion, and have so much development that you start as the #6 world power. The problems are that your main expansion routes are right into the empire, you have an old immortal wimp for a king, and you have serious religious problems.

1. You want to deal with the religious problems as soon as possible. You have two basic options. The first option, which is easier, but a bit gamey, is to pump up unrest in one of your religious provinces (send a missionary at no maintanence and then maybe lower the autonomy there if you can). Once you have zealot rebels pop, let them seige down your cap and you can convert back to the religion that most of your country follows.
The harder way (but potentially more rewarding in the long run) is to grab a point or maybe even 2 in stability, an inquisitor advisor (clergy can accomodate if you don't already have one), and then start converting. You may want to pick up religious ideas as well, but this isn't a must. Within about 2-3 decades you'll be fully converted, and since your neighbors are all the same religion that should be the end of your religion problems (until the corvinites show up)

2. Dealing with the expansion routes is difficult. You can definitely grab that lonely elf province next to you, but beyond that everything is imperial. You kind of have to live like a vulture. The Emperor will not generally want to pick a fight with you, but at the same time you probably can't win against both him and your expansion target and their allies. Yet. You have great military ideas waiting to be unlocked. On that note you are an elf. On top of the ruler weirdness I'll get to, that means you have better troops, better economy, and terrible!!! manpower. So you want to pick fights carefully. And you'll also want to get quantity ideas as your first military idea group IMO.

For now you have enough on your plate. Wait to establish yourself, wait out those dumb humans. Wex doesn't generally stay strong or the emperor. Once you think you are stronger than the empire, you can start making conquests (be careful of ae causing coalitions)

Another way to expand is to take expansion and go into the indie provinces you border. They are highly dangerous and populated, but your troops don't have much better to do than guard them (or you can take the native policy that turns off native attacks), and given time you can get in on the scrabble for escanor (and you are way more dangerous than the orcs or adventurers).

3. The other half of elven weirdness is their long lived kings. Their leaders always get a long lived trait, which makes them only die of old age at about 400. Once they are 300 they get occassional events that grow one of their stats, and far more frequent events that let you choose between 3 nasty penalties (IMO, always take the prestige hit over monarch points or stability). Most elves with 300+ leaders have really good ones, but you don't. You want this guy gone. Build relations with sun elf kingdoms to the waaaay southeast (in the middle eastish area) to try and get a royal marriage. If that doesn't work out, then just wait until you get an heir and/or wife pop up. Once he's got an heir, you have a choice. If the wife looks like she'd make a good regent, make him a general and try to get him killed drilling or fighting. If not, just wait until your heir is of age and abdicate. The heir doesn't have to be anything amazing, but should be better than his crummy dad.

Hopefully this will be of some help. If you have any questions or disagreements/I missed something please say.

U are amazing never saw this. Thank you so much.
