Aedra translated to "our ancestors in Elvish" and you are quite right in saying they took part in creation. According to St. Allesia, the Divines are the gods who gave up the most for the creation of Nirn, with Lorkhan being the "Missing God." Alduin however, is not an Aedra, but a simple powerful dragon, taking advantage of the dragon imagery of Akatosh, using it to propaganda himself as the "First born of Akatosh."
