how about adding bloodlines for legendary knights after they complete some special task/quest
and maybe change names of schools (Royal school for kings holdings, Imperial academy for emperors holdings etc) and maybe imperial academy should be more rewarding than royal school and more expensive

They're currently name Royal/Imperial School. I did fancy Imperial Academy but there is a mod, Universities, that has Imperial Academies. The university mod sits well with the school module and I use it myself, so didn't want the same name.
Although the cost is the same you need a Royal School to build an Imperial School.
In terms of being more rewarding, Imperial Schools have extra student minor titles and allow you to recruit Religious and Philosophy tutors.

I really like the idea of the bloodlines for legendary knights (though I need to tweak the requirements as too many are appearing for it to be legendary). I haven't looked into bloodlines so I'll need to see what options and possibilities there are

I've been toying with the idea of societies for knights & mercenary companies - both would be cross overs with other modules.
Societies & Knights would allow chivalric societies
Warfare & Knights would allow mercenary companies

awesome cant wait to see future updates .I actually haven't played the mod yet cause i have an exam on 17th but i will give more suggestions after playing. BTW maybe you can ask the AGOT mods devs for advice for their slavery system ?

I wish it were that simple. I've looked at slavery in the AGOT mod and it uses flags I believe regarding slavery religions and cultures. I've made mine to be more in flux
Slavery religions are dependant on the head of the religion (and their traits) so it should change over time, though one person can't suddenly change it.
Slavery cultures are defined by the landed characters of that culture, again the changes are slow.
Also, randomly there is an anti and pro slavery trait that characters get (though it's hidden)

I'm now starting work on training for knights - a less risky and less hostile form of duelling, next will be either vice and virtue of warfare module. After that I'm going to implement slavery auctions for MR's which will include slave breeding

ok then but you should make it so that Muslims buy the slaves with better martial stats and traits cause of the historic slave armies the Seljuk employed and of course the mamluks who actually ruled Egypt and Delhi(different armies) mamluks is the arabic word for slaves and truth fully the actual armies were composed of non muslims but i think there leaders were muslims and anyone who converted to Islam was freed. And maybe you can add a mamluk rebellion and ofc the seljuks also had some kind of slave army

While mamluks were purchased as property, their status was above ordinary slaves but they were not allowed to carry weapons or perform certain tasks. In places such as Egypt, from the Ayyubid dynasty to the time of Muhammad Ali of Egypt, mamluks were considered to be "true lords" and "true warriors", with social status above the general population in Egypt and the Levant. In a sense they were like enslaved mercenaries. (copied from wiki)

many slaves were also taken from ERE and Iberia and i think merchant republics like venice also dealt in slave trade . slavery was also present in England before william the conqueror . Sweden, Norway and Denmark were also slavers

The Swedish slave trade mainly occurred in the early history of Sweden when the trade of thralls (Old Norse: þræll) was one of the pillars of the Norse economy. During the raids, the Vikings often captured and enslaved militarily weaker peoples they encountered, but took the most slaves in raids of the British Isles and Slavs in Eastern Europe. This practice lasted in the 6th through 11th centuries until formally abolished in 1335. A smaller trade of African slaves happened during the 17th and 18th centuries[1], around the time Swedish overseas colonies were established in North America (1638) and in Africa (1650). It remained legal until 1813.
The thralls from Western Europe were mainly Franks, Anglo-Saxons, and Celts. Many Irish slaves were used in expeditions for the colonization of Iceland.[2] The Norse also took German, Baltic, Slavic and Latin slaves. The Vikings kept some slaves as servants and sold most captives in the Byzantine or Islamic markets.[citation needed] The slave trade was one of the pillars of the Norse economy during the 6th through 11th centuries.

Thralldom was outlawed in 1335 by Magnus IV of Sweden for thralls "born by Christian parents" in Västergötland and Värend, being the last parts where it had remained legal.[3] This however, was only applicable within the borders of Sweden, which opened up for later slave trade in the colonies.

Sweden had treaties with England[4][5] and France[6] concerning slave trade, with Swedish vessels involved in the trans-Atlantic slave trade

what i am trying to tell with these long wiki paragraphs is that everyone was a slaver during ck2 time. but muslim slave soldiers were treated a lot better

Btw you should mess with the grand tourneys, knights/rulers should choose a woman(might not be their wife) to give them their favor and maybe prize for the the top 3 winners and winner modifier (stackable)

A Tournament was a series of mounted and armoured combats, fought as contests, in which a number of knights competed and the one that prevailed through the final round or finished with the best record was declared the winner and awarded a prize, or purse of money

Tournaments during the Middle Ages were a good source of revenue for a successful Knight. The champion knight's prize money could yield a considerable purse. But at the tournaments of the early Middle Ages they were allowed to claim the armor and weapons of a fallen adversary during the tournament.

sorry for throwing so much your way but sometimes i get very excited about somethings

tournaments are on my to do list - for characters with the knight trait (though any count+ lord will be able to hold one). I like the suggestion regarding giving someone their favour and rewards for participation.

I have considered slave armies, and again it's on my to do list. I may create additional laws to allow it. Slave rebellions is the (current) end aim for the slave module when the rest is fleshed out fully (due to overlap between modules some elements will come much later than the initial module)

The slave rebellions I want to be potentially brutal. Once it starts as they successfully siege holdings and provinces they will release slaves (characters and buildings representing the slave workforce) thus reinforcing themselves. Obviously a nation with a lot of slavery is going to have a hard time, furthermore if they have slave armies.

With the exception of government types, everything is going to be available for all characters, regardless of religion and culture. I understand the game is partly a historic simulator, but I feel it should allow things to follow a less predefined path.

All that being said, different aspects/types of slavery are what I'm after. I can make it so that as the game progresses each culture and religion will change their stance on slavery - not simply for and against slavery as a whole, but being for and against different aspects and types of slavery.

I'll certainly come back to this once either warfare or V&V is released and look at further options whilst I'm developing the auctions for merchant republics.

Addition note regarding the auctions, they are auctions, so others will be required for the trade (like you mentioned slavery being a pillar of norse economy) and it would make sense for cultures/religions/countries benefiting from the slave trade to become more accepting & vise versa.

Anyway, thanks for the input. Whilst I have an easy time with scripting once I get into it, the ideas dont allows flow so help is much appreciated
