The giant jormungar have perhaps the strangest diet; they grow strong by eating the eggs of their own kind and the best eggs come from deep jormungar.
Were you able to get those eggs? Those worms will start eating their handlers if they're not fed soon.
Well done, <name>. I'll take these to the Argent Crusade's keepers right away. They'll have no choice but to acknowledge that we're doing far more than the Sunreavers to keep the coliseum running smoothly.
Sometimes a mole machine yielding a Stormforged Marauder will appear, instead of a jormungar. The Marauder can be left behind and will not aggro unless someone is within normal aggro range; they are not very difficult to kill, but drop no loot. They will despawn after a minute or two.
