Need More Talismans!

Dobber are you sure for: There is nothing that will prevent you from being allied with one of the "four" and the pirate at the same time

becouse i can't, i mean when i try it the second one always tell me that they will not join to my side if i have already alliance with some one else, no mather which one is the second, pirates or foreign culture.

well replace the pirates with other culture and it will work fine
the necessity condition is: the both neutral culture must be "free" non allyed with other player, and the diferent is instead of sinking a ships you must trade with them and get to the level 2 relationship.

but you don't get more colonial goods of your type so there is no point to do that
btw: if you already have an alliance with some of them and you broke it to try the above, your ex-ally wont offer you again an alliance ... atleast they wont do it for a long time.

This will not work between native cultures, as long as the offer of an alliance is on the table from one of them you cannot offer alliance to another without negating the offer from the other!
I checked it out in game!
