After siding with the Templars, I now have the choice to immediately start "closing the rift" quest. However, I am very hesitant to start this mission, because I am worried that the game, at least the main quest, will come to an end, and all major character relationships and dialogues will be terminated. I am not specifically asking for a spoiler, but rather some good faith that their is still more main quests to be completed after closing the rift. For example, uniting all factions together?
Does completing the mission "closing the rift" in Dragon Age Inquisition end the main quest of the game?
