Was just a little confusing as I just tried to match the components to the images in the rule book (where event cards and battle cards are depicted as having different backs.)
I can see where that would be confusing, not having the base game yet. The Event cards in the base game are divided into two different decks for each side, with different backs. Each Faction has two Call to Battle cards, with each one matching the back of one of the main Event decks. The Faction Event decks for each side included in WoME have different backs from either of the base Event decks.
