There are two new kill tasks given by the olthoi hunters at 43.7N, 54.9E.

Speak with Alicia Swiftblade and Tomihino.

Alicia Swiftblade tells you, "Greetings to you. I'm glad you've come up this way. If you're willing to aid us against these strange new Olthoi, I could set you to a task that you may find enlightening."
Alicia Swiftblade tells you, "Go out to the places where these new grubs have been appearing, and kill them before they grow into something far worse. Kill, let's say, 50 of these Paradox-touched Grubs, and I'll reward you for your aid in this. They seem to be most concentrated in the nearby valley, but I've seen signs of them all over 'Olthoi North'."

Tomihino tells you, "Greetings to you. I am glad you have come up this way. If you are willing to aid us against these strange new Olthoi, I could set you to a task that you may find enlightening."
Tomihino tells you, "In large numbers nearby, but seen throughout this 'Olthoi North', there are young Olthoi, those Nymphs of their species, touched by a strange Paradox of energies. Slay them, 50 should do for now, and return to me. Do this task and you shall be rewarded for it."

The easiest place to complete these tasks are in the valley below and the hives found in the valley. When you finish return to the NPCs for your reward.

Tomihino tells you, "You have done well. With the losses you have inflicted upon their young, it should slow their expansion considerably. I offer my thanks to you, and humbly ask that you return in a week, to help keep their numbers down."

Alicia Swiftblade tells you, "You've done it! That should help thin their numbers for a while. We haven't been able to stop them completely, but your efforts should help keep the lands safe for a time. Come back in about a week, and I should have more for you to hunt."
