Since the start of February 2017, this mod now has a new form of support for other modders, which is aimed at being able to fully customize any of the immortal faction leaders and any of the unique Lords and Heroes which I added, such as Karak Azul's Runelord Thorek Ironbrow and Mousillon's Wight King Krell.

Every faction leader, legendary heroes, legendary lords and every settlement now have unique units and settlement chains assigned to them which equal what is available in vanilla but can be fully customized to your heart's content.



The most important tables in relation to editing these legendary heroes and lords are:
agent_subtypes - Assigns the core data and unit to the character embedded in the startpos. The startpos also embeds the type of main_unit that a character has assigned to it, so modifying that in this table will do nothing, you will have to edit the unit data directly instead.
land_units - Defines the main stats of a unit such as the weapon and armor and more.
main_units - Builds upon land_units and defines secondary unit information such as unit caps, costs, voiceover data and more.
campaign_character_art_sets - Links the agent_subtype together with the unit's model and textures (variants). Other tables that are related to this are campaign_character_art_sets, agent_uniforms, unit_variants and variants.
units_custom_battle_mounts - Defines what mounted unit a character converts into by equipping a mount.
ancillaries_included_agent_subtypes / ancillaries_included_subcultures / faction_agent_permitted_subtypes - Enables items, followers or mounts for agents, factions and their subcultures.
ui_unit_bullet_point_unit_overrides - Adds "Bullet Points" such as "Damage Dealer", "Anti-Large" or "Armoured" to a unit's description box and is purely decorative.
campaign_map_attrition_unit_immunities
character_skill_***
land_units_to_unit_abilities


So every one of these custom characters now has all of the above tables assigned to them mainly based on their agent_subtype, land_unit or main_unit, which is named like "wh_main_<Subculture Tag>_cha_<Character Name>", so for example "wh_main_vmp_cha_krell" or "wh_main_dwf_cha_thorek_ironbrow".

Most things can be edited by editing all of the above tables, all of them should be labeled "custom_characters" in my mod. I worked with mainly existing data, so of course if you want to create something like custom items or mounts, then you will need to edit additional tables, but these new default characters are based on default lord data and refer back to the original character data as much as possible.

To create a new character I recommend creating the necessary tables in the above order.



Slot Templates are split into three parts:
Primary slot templates are for main settlement buildings.
Secondary slot templates are for all other buildings, such as military, defense, infrastructure and so on. Ports are handled as separate slot templates.

The database structure for assigning buildings to specific regions / settlements is:
regions >> slot_templates >> building_superchains >> building_chains >> building_levels >> building_culture_variants


All settlements that did not already have fully unique slot templates were given new ones to be fully editable. This means that all settlement building slot templates can now be found as "wh_main_<primary/secondary>_<Province Name>_<Settlement Name>", so for example "wh_main_primary_eastern_oblast_praag", "wh_main_secondary_lyonesse_mousillon"
or "wh_main_primary_zhufbar_zhufbar".

Settlements that can not be found in my slot template list already exist in the vanilla database with names such as "wh_main_special_carroburg_primary" or "wh_main_special_kislev_secondary" and can be edited in the same way as my custom slot templates.


So if you want to add a custom building that can only be built in a certain location (like for example the Great Slayer Shrine of Karak Kadrin or the Nuln Gunnery School), then you would create a custom building, assign its levels to a new building_chain, assign this to a building_superchain and assign it to the exact location via adding that superchain to the correct slot_template in slot_template_to_building_superchain_junctions.

If you want to remove or replace a building chain entirely, blank out the slot template and superchain columns in slot_template_to_building_superchain_junctions and create a new ID that is well above all currently used IDs to add your own. This will ensure compatibility with other mods trying to do a similar thing to the same settlement.
