In proto-norse the brothers Wódin, Wili and Wé (Odin, Vili and Vé) were the ones who slee the giant Ymir and ushered in the age of humans and the Æsir.
Proto-Indo European traditions hold that all of the gods, Æsir, Vanir, Olympian or otherwise are all representations of the same divinity, with the Sky Father (Diu, Ziu, Zeus, Ziupeter, Tiu, Tyr) as the "noble god" and the most sacred representation of the divinity. More on this later.
As aspects of the divine Odin, Vili and Vé's names come from the root words, and are aspects of inspiration, will and spiritual power (and nobility) respectfully. Therefore as a triad of worship, Odin was the means to knowledge and prayer to the divine, Vili was the representation of the divine's Will to fill someone with ambition and diligence, and Vé was the representation of the mysterious sacredness and power of the divine.
Roman Christianity follows the same tradition, denying the worship of the same divinity of the semite, instead for a worship of the european Triad. The Son, who fills the same role as Odin, a medium through which the mortal may access the divine (and who was also sacrified with a spear and a tree). The Holy Spirit is Vili, the force of the divine to inspire a mortal, and the Father is Vé, the mysterious sanctity and power of the divine. The name of God in Latin, as we all know, is Deus. This word has the same root from which Zeus and Tyr derive their names, as mentioned above, in favour of the semitic names of Yahweh or Jehovah.
Furthermore, aryan and particularly slavic and germanic religion upholds a typical class system. The three classes each represented with a god.
>The nobles (Odin/Perun/Apollo/Mercury),
>the preachers (Tyr/Radegast/Zeus/Jupiter),
>the workers (Thor/Veles/Dionysios/Dionysius)
