Prevailing theory is that ESO takes place during a Dragonbreak, so lots of nonsense can happen out of time and out of order. Dragons are upcoming, and somehow we’re going to be releasing them on accident in the next DLC. UESP cited some dev-talk that female dragons called Jills end dragonbreaks, and my guess is that in the next DLC, we will try to awaken some Jills to put time right but goof up and just awaken some dragons instead.
