Thulecite

"Is pretty rock."

- Wolfgang

Thulecite is a material found in Ruins. It is used to craft various items in the Ancient tab and to repair a broken Ancient Pseudoscience Station. Currently, it is nonrenewable, though in theory, one could renew Thulecite by hammering the Ancient Pseudoscience Station and repairing it, since it takes 10 hits to destroy the Station but only 6 Thulecite to fully repair it, and each hit has the potential to spawn Thulecite. The chances of this occurring are extremely low though, so for practical purposes, Thulecite is non-renewable.

Slurtles and Snurtles will attempt to eat dropped Thulecite, and Slurtles will attack a player holding Thulecite if there aren't any other minerals around for them to eat.

In the Reign of Giants DLC, Thulecite is renewable by hammering Thulecite Walls to get Thulecite Fragments and then using the Construction Amulet to make the cost of three Thulecite fragments instead of six. This can only be done in the Reign of Giants as Green Gems are only renewable using the Tumbleweeds from the DLC. This is a gain of 4 Thulecite per amulet.

Trivia

 * Like much of the Ruins, Thulecite was inspired by the Cthulhu Mythos, deriving its name from the name of Cthulhu, an ancient god-like being associated with insanity, magic, abnormal geometry, and tentacles.
 * A secondary inspiration for the name may have come from Thule, a far northern region in ancient geography that is usually described as being the farthest north one can travel. Later writers used the term Ultima Thule to describe something far off and unatainable. This is probably a reference to Thulecite's status as an endgame material.
