Notes:

Thorbin is worried about the melting glacier and sends you down to the depths to investigate what is going wrong. Head southwest to (-760, 60, -200) and you will see a Traitorous laborer standing in front of a brew barrel. It should update the first step here and then a few seconds later the second step will update and the Laborer will attack. Kill him (if you die or run away, any laborer should suffice) and return to Thorbin. If doing this for multiple people it is likely best to have only one person have the task at a time.

Next he wants you to collect a few things for him. He gives you a Cooling Chamber Navigational Assistant. This is a clicky you can use while invis to help guide you towards a specific barrel in one of the caves. Once it changes from the "nowhere near" message to the "not quite there yet" message you know you are in the right cave. Clear out any kos goo (the yellow con), /open a barrel, and /loot it. While clearing the room be sure to loot a Stonegrind Solvent as well (very common). The Caveflower Pollen is a ground spawn found near the zone in under a flower. The step for the Reagent Corruption Plans will randomly update on the death of any traitorous mob (you may need to kill many before it happens).

Once you have all four items return to the spot you found the initial laborer. There is a "Reagent Mixing Container" (brew barrel), combine the four items inside to create a Purifying Cooling Reagent. Deliver the Reagent to Thorbin to complete the task.
