I just keep having this dialouge
"Can you make me Blood-kins?"
the answer is always the same with " Trust like that is not freely given" from every single Orc of Skyrim
Anyone know what is this?

if your blood-kin you can enter the orcs strongholds, you do this by doing a simple fetch quest, or at least that's what i keep getting...

its to get into their strongholds, none of them will make you blood kin, unless you do a mission for malacath or an orc stronghold

You can also just help out orcs not in strongholds. The orc miners in the Reach usually end up making me blood-kin.

I did what they ask me:
Find this finger forge( I dont know how i got 2 of them but I gave 1 to the tribe)
Brawl thier leader
help the Orc who having trouble

I still can walk into thier strong hold freely with no trouble.I just wonder what is this "Blood Kins" is

Also fetching a book for the lorekeeper in the College of Winterhold will result in him making you blood-kin

That's just a glitch. If you complete the quest, you are named Blood-kin, but you still get the dialogue option.

You're already Blood-kin.

Thanks

Yea and Blood-kin is just an honorary member.
