Fei/Id/Graf; The -Contact- (Xenogears)
The -Contact- is the human that made contact with god within this 4th dimensional tier. God was trapped within the pseudo-perpetual infinite engine named Zohar and wanted to return back to its domain. In order to do so, it bestilled within the 6 year old boy Abel his power. From there, the -Contact- Abel is reborn; until his task of freeing the Wave Existence (god) and allowing him to return home.
While there's been upward to 10 millenniums worth of -Contact-, only three are noticeable. Fei; the main protagonist, Id; Fei's alter ego, and Graf; a reincarnation of Abel that experienced incomplete contact
