Assassin's Creed

Im not sure if Im being a bit dim (lol) but how do I get my assassins from lvl 14 to master assassins? They wont rank up anymore and I cant see a black coloured den to assign them to.. There are no master assassin missions left to do and I only have 4 master assassins, a few 14 's and the rest 10. I know I cant up the lvl 10's but Im stuck with the lvl14

p.s. i have locked dens and unlocked dens but there are no glowing bits in the unlocked dens to assign anyone to..

Once they reach level 14 you can assign them to a den I think by actually going to a den that shows a "master assassin" mission

double post but never mind just this once..

you can only assign 1 master assassin to each den so if you have some dens locked or under borgia control then you need to free those ones before you can assign an assassin to be the master of it
