It is a decision.
It say it right there on the society rank power's tooltip. Who am I kidding, people do not read tooltips/instructions. I should have known that, I work in customer services.
If you do meet all the requirements, click it. It, the decision, appear at rank 4.

Could you create a template for a new update now that we have the bloodlines on holy fury?

Mmh, template? You mean something like my society tutorial mod?

No I'm sorry. My English is not so good. I would refer to appearing the bloodline, just as it appears in the holy fury.

I am sorry, I still do not really understand.

Most bloodlines in Holy Fury appear randomly, I doubt that's what you want.

English is not my first language either. Ce serais-tu plus facile en francais?

One of the requisites is to have a guarded, decorated wharehouse with Important documents. I have decorated the wharehouse in all possible ways but I don´t know how to guard it and put in my Important documents. I´m Guild Master so I should be able, right?

Guarded Warehouse is the level 3 warehouse building (rented - normal - guarded). Important documents is from an intrigue decision, it give you a "documents" artifacts that work if you have a warehouse.

I guess that this is an issue of using a more "role play" description instead of a purely informative one.

Good afternoon, in regards to the bloodline is there anyway to gain the master trader ability if you rejected the apprentice trader chain very early.
If I had know the requirement for the bloodline in advance I would have taken it but at the time the diplomacy minus would have been a problem.

Also with no way to restart the chain as far as I know I feel this is a somewhat unfair requirement compared to the others listed.

Ooh, mmh, I could attempt to find a solution to that in the future. Perhaps simply having the right amount of "trade xp" even if you do not have the trait could do.

You could "cheat" and use this console command to add it meanwhile:

add_trait guilds_trait_master

Hey mate, Im a bit confused about the bloodline. How do you get the guarded warehouse? I have searched up and down the intrigue menu and have it fully upgraded and also have the documents. is there anything I can do to to upgrade it to a guarded warehouse? i just need this and a bit more trading

I thought that I had a button for that, but I reworked that system so many times that I forget which is what.

I think that you can upgrade the building to have guards from your capital building tab but upgrading the warehouse building.

any tips on the trade war?

The more spending power on a side, the stronger it is. The more kings/emperors there is outside of the league, the harder it is for the society to win. If you aren't a member then it'll be risky to participate and vice versa.

Spend a lot when prompted, of course. But you aren't the only one so your effort won't win the war by itself.

In case all of this is too annoying, you can disable it with a game rule.

yeah
