Magic Mirror beta v0.3 for Strive 0.5.24c. You can add this mod to an existing game or start from new.
To start the quest, go to the mage guild and ask about your uncle. Even though you can start this quest on day one it may take many days to progress. The mod ends once the mirror is gone. You can then unload the mod and keep the rewards.
This mod should work with random portraits. V0.3 has cut out all the items in v0.2 so it is much more compact and durable, hopefully. The story is the same as V0.2.
