An Untimely Mirage is an era-spanning time-travel adventure that plunges 4–6 level 1 heroes into a battle between goblin bandits and an elven town. The initially typical adventure setup is flipped midway through, as a terrible storm drops the heroes into a mysterious civilization and time period where everything is different. Will the heroes return home the same people they were before? Can they use the lessons of the future to build a better present?
