Athens starts as Macedonias client state, what does it mean?

[Gauloisier de la Gauloiserie]

Hi there
When you play with Athens you start as Macedonia's client state. I ask that here cause I cant test it right now, only tomorrow evening... are you totally free of your moves, decisions, war declarations and such? DO you give a % of your income to Macedonia? Can you, right from the start of the campaign, say to Macedonia that it's over, and become independent?
Thanks for your help

C'mon I'm sure some of you have played the campaign and checked the income: are you giving money to your Macedonian protector or is the whole client state thingy much more of a normal alliance + role-playing element in the case of Athens?
Thanks a lot for replies!
