Icaria is a city located near The Wall and is accessible by a minecart track that passes through The Wall. There may be other methods of getting there, such as by airship, or via Fumblemore's botched teleportation attempt. Icaria may be one of the last cities left in Minecraftia that has not been demolished by someone affiliated with Israphel or his cult.
In the destruction of Mistral City, Father Braeburn fled to Icaria, along with the unseen Mrs Miggins, who had found her cat, and presumably Mrs Perrywinkle. He asked Xephos and Honeydew to retrieve the Golden Record from the burning ruins of the church and return it to him in Icaria for a reward.
It is also known that Fumblemore teleported his tower to Icaria, though he made a mistake in the spell casting, resulting in his tower arriving upside-down.
Icaria has not yet been seen by our heroes, but may be visited in a later episode, due to the amount of characters that are currently living there. In Minecraft - "Shadow of Israphel" Part 24: The Fiend, Isabel Peculier said she would be sailing to Icaria.
The only known way the town can be accessed is by taking a minecart down a minecart track located on The Wall.
The city has been seen in some mod spotlights. In the city, there is a giant structure made out of glass and stone, as well as a castle of some sort. Icaria also contains a giant telescope which points out to the giant stone dragon near The Tomb of Lehparsi and Skylord Jasper's ship has also docked in the town's bay.
