Grummore

A mysterious being, with little known about him or his origins. What is known, however, is that he has been Lyras' lifelong enemy, and posseses the chaotic and destructive power known as the 'counter-essence'. He also seems to strangely resemble the race of Grimace, but was never born on Grimrock.

"Have you tapped into 3News yet? It says that Grummore was spotted in the same area as Lyras."

Grumman LLV

The Grumman LLV (long life vehicle) is a compact, right-hand-drive mail truck designed specifically for the United States Postal Service (USPS) and introduced in 1986. Built by Grumman using a General Motors chassis based on the Chevrolet S-10, the LLV features an aluminum body and a 2.5-liter inline-four engine. Its design prioritizes functionality, offering a tight turning radius and a low-geared, three-speed transmission suitable for frequent stops and curbside mail delivery. Despite its utilitarian design, the LLV has become an iconic symbol of the USPS, known for its durability and distinctive appearance. The vehicle's longevity is a testament to its design, with many still in service today, even as the USPS plans to replace them with newer models.

Waiting for a letter from my pen pal in Brazil, I stood at the mailbox for 2 and a half hours as i was exited to get a response from him. Then an old slightly beaten up Grumman LLV appears from the corner, it’s brakes screech as the vehicle came to a full stop. the driver an old white guy in his late 70’s open the door of the LLV and said “are you Mandy McAdams”. I said “yes that’s me” then he hands me my letter and then I opened the letter excitedly to see what my pen pal said.
