Yock Island

Yock Island is a small isle located in the middle of Kauroy Lake near the southern Amestrian town of Dublith. It was here that Izumi Curtis sent the Elric brothers to test their abilities in preparation for apprenticeship under her. They were to survive on Yock, alone, for a full month without the use of their alchemy. Additionally, she tasked them with figuring out the meaning behind the phrase "All is One and One is All" by the time their month was up. Though isolated, Yock Island seems to be teeming with all sorts of wildlife such as birds, toads, snakes, rabbits and foxes.

In the 2003 anime Yock Island was considerably larger, being made up of several large mountains. It served as the secret birthplace for Izumi's failed human transmutation, the Homunculus Wrath. For years he lived alone within the forests of Yock until finally being discovered. Eventually, the island would go on to be literally split in half by one of Izumi's attacks, destroying a larger portion of it.

Supposedly, Dante's manor was located relatively close to this lake. It also was the host to the battle between the Elrics and Wrath and was the first time they met the Führer knowing he and Juliet Douglas were Homunculi.
