Marworyn ap Cran' Dohain, the Ember of the World Tree, is an artefact belonging to the Vaelaros Clan, gifted to them ages ago by the Queen of the Fae. Marworyn is made of the sap of the World Tree, called Cran' Domhain in Sylvan. It holds the power to call on the World Tree to open any dormant or closed portal before it.

Marworyn is wielded by the Champion of the Vaelaros Clan, and only they may use its powers.

Marworyn is a special artefact able to take on the shape of whatever weapon or instrument its wielder requires.
