Dialogue
 * "Each year during Wintersday, the gods Grenth and Dwayna clash to determine whether darkness or light will reign following the coming of the new year. Although Dwayna has many followers, there are some of us who understand that this is a season of somber reflection, a time to pay tribute to death, which is, after all, a necessary cycle of life.  The call of Grenth has gone out, seeking all those who wish to serve the Merciless One to ensure his rise above the goddess of light for the coming year.  Will you answer Grenth's call?

Walkthrough
None of these items will actually show up in your inventory, you just need to talk to the specific NPC to get them:

Termites
Termites are on the beach in North Kryta Province (see map).

Talk to Fisherman Finnius by the dock. (Note: If you have the Defend North Kryta Province quest active, Fisherman Finnius will not appear. You'll need to finish or abandon that quest before you can find him.)

Gunk
Gunk is southeast of Temple of the Ages (see map).

Follow the path across 2 bridges, Gunk Farmer Urme will be on the left in the swamp.

Garlic
Garlic is north of Beetletun (see map).

Find Necromancer Skorzena and her Elite Guards who are battling the Nobleman Daltain and his guards. You can help her or sit back and watch. As soon as Nobleman Daltain is dead you can talk with Skorzena to receive the garlic.

Unwashed socks
Dirty socks are just outside Bergen Hot Springs (see map).

They are stolen from Villager Gessel by Dreier Dane. Chase Dreier Dane down.

You must "chase" Dreier until he decides to stop. If you use a speed boosting skill and "tag" him before then, you merely receive a generic NPC statement.

Destroy all wintersday gifts
Once all the items are acquired, talk to Vehemus then leave from Lion's Arch to pick up the Grentch and destroy the presents (7 total) in the Ascalon settlement; click on a present to destroy it. Destruction of the Brrrls (5 guarding the presents, 3 at the north gate) is optional. If the Grentch dies along the way, the quest can still be completed sucessfully.
