Free as a Bird quest is connected with an option that allows you to join one of the three factions in Elex – Berserkers, Clerics or Outlaws. This quest is added to your journal when you speak with one of leaders of the previously mentioned factions and it's updated when you meet with leaders of other groups. In order to gain their favor and get a chance to join them, each faction requires you to perform a series of quests.
Warning – Being a hindrance to a given faction can make the process of joining them much more difficult or make it impossible for you to join them.
