Horizon is the most accessible entrance to the Calcific Isles, the third and least explored of the great Labyrinths. The city was built in a small peninsula of “normal” land extending into the Labyrinth’s waters, and is surrounded on three sides by the Labyrinth’s shallow but deadly coral reef system. Named for the vast horizon line of the Labyrinth visible from the city’s docks, as well as for the more metaphorical new possibilities that the Labyrinth represents, the city is a symbol of hope and discovery to the Republic’s people. Over the last few decades, the task of exploring, charting, and discovering resources within the Calcific Isles has become a major goal of the Republic’s government. Thus the city, originally a small town of ragtag Delvers, has boomed with all of the new attention and the wonder of exploring its depths has caught fire in the Sunderwyl peoples’ collective imagination. Even the Artificers decided to move their guild headquarters from Ironwall to Horizon to assist with expeditions into the dangerous labyrinth.
