Basically these Gothic wizards based off the Four Horseman of the Apocalypse (although one of them was killed moments earlier) trick the fairies and open up a void that threatens to destroy them all, and Nabu closes it up, but uses all his power to do so and goes into a coma-like state which many treat as death although it is said he will wake up eventually. (Season 4 is series finale for me so I don't know anything that goes beyond that in Italian or Nick versions)
