You will be required to fight with whatever faction your race is bound to. Guilds however will be cross-faction so you can join an Ebonheart Pact guild, this will only apply for pve however because once you join a campaign in Cyrodiil you and your guildmates will be seperated into different campaigns. Guilds are account wide, you will be able to join 5.
