There may be some merit to the theory of the Outlander being the representation of Nahut for the Zarkuulans.
Nahut, reviled as the Hated Son, was one of the six primary Old Gods, the deities worshiped by the people of the planet Zakuul prior to Valkorion's ascension to Immortal Emperor. One of the four children of Izax and Scyva, Nahut was considered to be gray, formless and cold, and was denied worship by all except his mother Scyva. The Old Ways taught that Zakuulans should not follow Nahut into darkness, but should instead "light the way" to bring Nahut home.(Source: Wookieepedia)
Thus we may be the fourth child of Valkorion given his penchant for merry body-hopping.
Or through him infusing the PC with his power wether you submit willingly or get it when he blows up.
