Gotrek ends up getting deified
His final adventure is called Godslayer. He actually punks a full-fledged deity and ends up ascending as the god of Slayers. He becomes the target for aspiring Slayers who seek a mighty doom. His only hope is that a Slayer takes his deific mantle from him. By force.- CONFIRMED! He gets punked by the original god of Slayers, and then is bequeathed his mantle.
Gotrek's axe is one of the twin axes of the Dwarf god Grimnir
One of Grinmir's axes is in the possession of the Dwraf High King. The other is thought lost ages ago. Apart from explaining why it is so much more powerful than other mighty artifact weapons, when Gotrek and Felix had rules back in the 4th Edition of Warhammer Gotrek's axe had rules that were exactly the same as the Axe of Grimnir wielded by the High King - except that Gotrek's axe gained additional benefits against Chaos where the King's axe gained benefits against giants. This is pretty much confirmed in one of the final books by William King, when explaining where Gotrek found his weapon.- Confirmed: Gotrek and Feliz meet Grimnir, who confirms Gotrek's axe is an Axe of Grimnir and fully-powers all its runes.
Gotrek's destiny is being shaped by Grimnir
In Giantslayer, Teclis theorizes that the axe is the work of a god and that Gotrek is its chosen instrument. After the events of Realmslayer Gotrek actually is Grimnir
He's still got all of the divine power boosts Grimnir gave him minus the eye, and the rune he carries represents both the biggest single collection of Ur-gold and most powerful rune ever assembled in one place. If he's not the god himself he's almost certainly on a power level short of nothing but the gods now.- Jossed in the sequel. He's carrying a bit of Grimnir's spirit and when the Master Rune is at full power he can go toe to toe with avatars like those portrayed on the tabletop, but a god is as much the spirit of an entire realm as they are the bodies they inhabit. He was initially under this impression himself (especially since Teclis is a god now), but Alarielle effortlessly disabused him of the idea when they met in person.
