Wolfen is one of the three moons orbiting around the world of Crossfire. It is said to be the spirit of the legendary hunter Wolfen, who tracked Kalkaruntes, God of the Dragons, to is cavern and vainquished it.

In astrology, Wolfen is the symbol of practical mind, swiftness and flexibility, but also cowardice and stealing. It is associated with the Earth element in Alchemancy. Wolfen is seen as a protector by hunters and rangers. Priests of Lythander think it is the reincarnation of the wolf that hunts with Lythander in the divine forests of Nerënna. Fenxes see it as Fixas, the one that saved them from the Humans so long ago.
