That is intended and meant to be like that both for lore reasons and to make it possible for overhauls to better edit these factions with custom unit rosters, like how Cataph has it planned for Karak Zorn.

ya i realised when i started using the graybeard expedition. they had all units.

in the faction selection it says that if you restore the trade routes you can recruit elite units cause youre forgot by the other dwarf, but I do not know how to do it because I already trade with karaz a karak and did the underground trading technology and nothing worked. There is some way of being able to recruit them or it is directly impossible?

Once you established trade routes you should get an event message after which you should be able to build higher tier artillery buildings and recruit all units. If that does not happen your campaign is either pretty old and was started before the update that made this possible was implemented or you have broken scripts and this, alongside tons of other functionality is broken.

Are you using the Community Framework? Do you see a Rites button at the bottom right without using a mod for that?

I use community framework and dont see rites button but thank you soo much for answer now i have hope xD, i'll chek it and if dont appear i restart the campaing ;D

Somewhat related, seems better to post it here than make a new thread, is there any way to unlock the rest of the dwarven units playing as Karak Zorn or Karak Dank in the vortex campaign, since there's no way to make a trade route with the old world dwarves. Unless Greybeard's Prospectors count as an old world dwarf faction? I mostly just want to play the vortex campaign for the shorter turn waits, but if there's no way to unlock the full unit roster in the vortex campaign I'll just swallow the minute and a half turn waits and play in ME. Thanks in advance!

Greybeard Prospectors are indeed counted as Old World faction, so they are your only option.

Great job on this, btw. This is the kind of thing that makes the smaller faction campaigns more fun.

Keep up the amazing work.

Excellent! I really do like that mechanic, and I appreciate the reply.

I really love this mod. Playing as Karak Zank I got the event that should have unlocked all tech but it didn't. Reloading the game didn't work.
It's sad because I don't want to play them without my favorite unit.(Irondrakes) Really like the idea though.

How to establish a trade route?

But what am I to do if they were destroyed and I was unable to trade with them before that?

Then you are out of luck in the Vortex, though you could use another mod to revive them or settle their territory, provoke a rebellion and let them take over their previous capital to reform their faction.

Thanks. I will have to try that then :)
