A Quest is a topic two souls explore together on a call, guided by thoughtful questions served one at a time.
Either of you can ask for a new question; you move on when your partner approves. If nobody moves things along, the next one arrives on its own after a few minutes, and the timer pauses politely if one of you drops out for a moment. The last question loops gently back to the first, so a good conversation never hits a dead end. Your progress is saved per pair: talk to the same soul again and the Quest picks up where the two of you left off.
Free Quests can be used with any soul match, as often as you like. Premium Quests are unlocked per soul match; there is a separate article on those.
