In Sparta, there is a Spartan general who needs your help with massacring some Athenian Polemarchs. He will be near the Tomb of Leonidas and his quests act a lot like a certain Athenian general's. This guide will go over his quests and the main rewards that you will obtain by completing his side quests.

If you want to explore a different region, head back to our Assassin's Creed Odyssey side quests guide for a full list of the different regions. Alternatively, there is also the Assassin's Creed Odyssey guide for everything else this massive game has to throw at you. Also, for the sake of clarity, it is always going to be the Athenian seals you'll need as Demosthenes requires the Spartan ones. More on his quests in our Demonsthenes guide.
Much like Demosthenes in Athens, Lysander in Sparta wants you to kill Polemarchs and retrieve their seals. Only instead of Spartan seals, he wants Athenian ones. Kill and retrieve three Athenian seals to complete this quest for a financial reward and Lysander’s Belt.
Only Fools Want War
Return to Lysander and he’ll not be fully satisfied. So he’ll want you to kill three more Athenian Polemarchs and retrieve their seals. Once you’ve done so, return to him to get Lysander’s Boots, as well as some drachmae for your efforts.
The Cost of War
Once again, Lysander wants you to murder three more Polemarchs and retrieve their seals. Do so to complete this quest and get some drachmae and Lysander’s Chestplate.
Know Your Enemy
This will be the last time that Lysander in Sparta wants you to kill Athenian Polemarchs and retrieve their seals. You know the drill by now, so head over to the nearest Athenian location and kill the Polemarchs there. Complete it to get some money and Lysander’s Gloves.
That's all the side quests for Lysander, but there are plenty of others who will need your help. Head on back to our Assassin's Creed Odyssey side quests guide for more information about another quest-line or another region's set of side quests.
