The First Ender Wizard is a ancient wizard from near the start of Elementia. Much about him is unknown, but he is an important figure in history.
The Ender Wizard was supposed to have come from The End, and he entered Elementia soon after it's creation. At some point he had four daughters who became known as the Elemental Witches. He gave each of them an Elemental Scroll, in fact the split Ender Scroll. It is unknown why he did so, or how he gained the Ender Scroll, but he vanished soon after.
Research by the modern Ender Wizard Dragon suggest he might have stolen the Scroll from The End, and went into hiding to avoid The End ruler. It is believed the underground structures known as Strongholds are connected to the Ender Wizard.
