Effigy is an alchemist who starts the Tower of Life. During the quest, he and the other alchemists, Transmute and Currency summon the Homunclus, but they torture it and threaten it. In the end, they are scared off by the creature and their whereabouts are unknown.
If you have completed Making History before starting the quest Tower of Life, then Effigy will make an angry comment about a foolish adventurer, who stopped their plan of building a new tower where the Outpost is located, due to a renewed interest in making it a museum. Your character will try to evade his questions, but with little success.
