Adhur means "magic strength" in Euskara, the language spoken by the Basque people who inhabit the Pyrenees in north-eastern Spain and the adjoining region of south-western France. This word is related to the moon, being personified by the supreme goddess of the ancient Iberian pantheon, Anbotoko Mari, worshipped by the Basques until the advent of Christianity. Eate, the leader and founder, chose the name because it defines his purpose of expressing the real meaning of his being and his spiritual and musical relationship with the ancient Basque world.

Later Egoitz joined the band and so the band was established as follows: 

Eate - guitars, percussion, vocals
Egoitz - bass, keyboards

The three songs recorded for this split CD belong to the Basque mythology and cosmogony, and each of them is closely related to this fact. "Sua" (Fire) means creation, the beginning, and at the same time it is the first song. The following, "Akelarreko Batzarra" (The Gathering of the Akelarre), deals with the return of the legitimate owners of the earth, the real gods, and the mention of the akelarre represents the germination of the seed, because akelarres are fecundity rituals of the goddess Mari, the most important one in the Basque mythology. The third song, called "Iluno" (Darkness), an ancient word found in a prehistoric Basque tomb and written in ancient Basque, deals with the death of this person and his conversation with the goddess Mari, who is embodied by the moon. Thus the cycle finishes with the Birth, the Fertility, and Death, the natural cycle of life. 

The mentioned musicians in past members collaborated in those three songs.
