Zesk

Zesk is a secret Rank 1 Networker from the 2009 BIONICLE theme. Zesk will only be friends with players who have the Thornax Stew blueprint in their inventories.

Sending Zesk a Thornax Stew gains players the Musk of the Vorox (formerly Musk of the Bonehunter.)

His description reads:

"The bestial Zesk lurk beneath the sands of the Bara Magna wastelands, ready to attack anyone who passes by."

On his page, the Zesk Sticker is available for 3 Thornax.
