It says you can get 6 Thrall Wizards for one Greater Minion of Chaos talent, in Tome of Fate.
It says you are limited to your Fellowship bonus in minions in core.
It also says you are limited to your Fellowship bonus in thrall wizards in Tome of Fate.
Since you get 6 for 1 talent, should it be considered that all 6 Thrall Wizards you get with Greater Minion of Chaos count as 1 minion for the general-Fellowship limit, and that you additionally can't have more than your Fellowship bonus in Thrall Wizards as well?
In other words, my interpretation is that a Fellowship 60 Thousand Son could have, for instance, take the Minion of Chaos talent five times (to get 5 rubric marines) and then take Greater Minion of Chaos to get an extra six Thrall Wizards. Does this seem right?
