The Peloponnesian League

The Peloponnesian League was a virtual representation of one of Kassandra's genetic memories, relived by Layla Hassan through the Portable Animus HR-8.5.

Description
Peering through the billowing smoke of war were the red eyes of the Cultists' Peloponnesian League, a small group that would stop at nothing to turn all Greeks into Spartan slaves.
