Zylonika is city in the Desert River Province on the outskirts of Irondune named after a magnificent king. It is a two days journey from Zylonika to Finbar.

When the worst of the hauntings of the Nemesis began early in 946 GUE, this city was within the zone known as the Forbidden Lands. Thousands of refugees and lunatics streamed forth from the city, leaving behind a desolate and dismal place. One of the only to stay behind was an old woman who had once been an alchemist in league with Erasmus Sartorius.
