all possible satellites spellforce 3 (SpellForce 3)

in the game there are achievement friends the criterion for which is -
You drew to his side all possible satellites. but according to steam, no one was able to get this achievement.
So maybe together we can find the key to this achievement :)
The story of spellforce 3 tells us of a time before the creation of the circle of mages which included 13 people of different races and most of them is our companions in 3 parts.
Let's start from simple to complex, characters that are impossible to miss:
1) Iria - our first satellite after the prologue. you cannot miss
2) Isegrim - 2 satellite. also you cannot miss
3) J. - get together with the army people. personally, I believe that he will not become the magician's circle, though he was a character with the same name in part 1 and he was a mage of the circle http://ru.spellforce.wikia.com/wiki/%D0%A0%D0%BE%D1%8D%D0%BD_%D0%A2%D0%B0%D1%85%D0%B8%D1%80 (Rohen Tahir)
4) the Mountains get together with the army of orcs
5) Ongar arandir - also impossible to miss, but the magician's circle will not be
the characters that join after additional tasks:
6) Uram - get to options you specify in the location of the foot of a gaff-mountains
7) Andergast - get to locations vsesvet in the Guild of creators
8) Anna - to be honest I do not remember the location in which we find it, but miss it almost impossible
characters whom I could meet,but they don't join me:
9) the Shaar - meet on the Islands in the distant sea, but no matter what replica I did not choose, he did not want to join me, only helped in the last mission giving the serpent squad.
10)Raita Black - a dark elf who helped us to remove the miasma, to help the elves and improve their troops, as well to join me did not, if anyone can lay describe how you did it)
the characters who will be future mages of the circle, but the game never met, most likely appearing in DLS:
11) Hokan Ashir
12) Silverhand
13) Zaheer Snake
14)Playing the flute ( Yes, a single mage circle, whose name is not known).
It's possible that the only possible characters that I failed to attach is black Raita. so if someone joined it then share how you were able to achieve :)
