Is it 
that is hunting 
in this story? if it is did travel to Ixtal or did travel to freljord? its probably not maybe it was intended to be back when was released but i just dont see how they can link up now days. Just wondering.
You're right, it's an old story but that doesn't immediately make it non-canon.
It's implied that Rengar is the narrator, he also narrated the new Kha'Zix Color Story. As to who went where, I guess Gnar ended up in the Jungle somehow?
Well... yordles have magical portals that let them travel between places of Runeterra... so, that could explain why Gnar is in Kumungu.
