Naldiq & Vymelli's shipwright Hezzkhezl needs help heating his rivets.
Journey outside of the Moraby Drydocks and slay three lightning sprites for their cores.
You have collected three intact cores. Now deliver them to Hezzkhezl.
Hezzkhezl is delighted at your return, and tells you that it was Victory foreman Ahtbyrm who originally conceived the idea of using sprite cores to heat rivets.
Leviathan's eye! Ye really done gone an' fetched me the blinkin' cores! Ahtbyrm'll be right pleased to see that, he will.
'Twas the foreman what came up with the idea to use cores to heat the rivets. A clever one, that man. Sharper than a fang in a fishback's beak. Probably is why he made chief so quick, like.
