Raxlith

'Raxlith' can refer to one of two things. The first is a mineral called 'raxlith.' The mineral was named after the magic user that discovered it. The mineral can only be mine in the Wastes, and has many unique magical properties. Its most used property is the ability to hold a human soul after death. It is used in human tombstones to protect/trap the souls of the dead to prevent the Titans eating them.

Raxlith the mage was Cainin's first Worldbreaker. He was originally a powerful beast shaman who become obsessed with humans. After absorbing a human soul he became human. This allowed him to indulge his obsession and join the ranks of the Master Weavers, who were unaware of his origin as a beast. As a Weaver and a shaman he mastered both growing and weaving, which allowed him to invent the third form of magic, Necromancy.

After discovering raxlith the mineral and building his tower in the Wastes, his true destiny as a Worldbreaker was revealed to him. Reports are conflicted after this point, but it is clear both an army of beasts and humans marched into the Wastes to prevent Raxlith from fulfilling his destiny as a Worldbreaker. Raxlith seems to have thrown himself from his own tower before the arms reached it. Thus, he prevented himself from succeeding as a Worldbreaker and a second Worldbreaker, Solis, become necessary.
