Starting location: Talk to Lysander
Description: The mission requires you to collect 3 Athenian seals. To find one, you’ll need to head to an Athenian stronghold and kill the polemarch. Having killed him, collect the loot to acquire a seal.
This mission is not the only one of its kind. The missions will be repeated until you get enough seals. It is worth doing these missions to gain a lot of experience points (for killing the polemarch and for completing the task).
