So, Epeirotes Approach Me

[A Terribly Harmful Name]

It's about 258 B.C, I'm the Aedui and got an offer from Epeiros to send one or two armies (can't remind exactly how many) to solve the Epeirote barbarian problem by taking Vindobona and Ak-Ink. The Romani are under control now (I've taught them a lesson) so I accepted it and am currently training Bataroas for the campaign.

My question is: how many of you actually fulfilled that mission? Those two cities seem too far away from my Gallic homelands, yet an alliance with Epeiros for now is a good prospect. Besides they are still my VC's, so it should do me well to take them and fortify them before the time; the only problem with this grand strategy are the Getai. How much time do I get? And do I get another reward for that? Do I need an expedition just now or may I leave it for when I am bigger and better and start expanding around there?
