The Book of Knowledge is a book contained in the Nexus, seen in the "True Ending" of Legend of Grimrock II. It is quickly leafed through, showing a vast array of information contained within its pages.


The scene must be paused to glean anything from the book's pages, due to the speed at which they are turned. A cipher hides the content, but it has been partially translated[1]; the use of the names of Mount Grimrock's levels helps make the translation easier. Several of the pages contain information about the history of the lands and their culture, though the turning motion makes some sections too illegible to make sense of. Various images accompany several of the excerpts, including Zarchtons and maps of real-world pyramids. A passage of computer code is also found within. The final two pages show maps of the locations visited through the series so far, Mount Grimrock and the Isle of Nex. The following table shows the page images and their translations:[1]

1 - 1 study of zarchtons

zarchtons are amphibious creatures
that are at home on dry land as in
water, but they never leave too far
from water, because they are depend-
ent of moisture and need to dampen
their skin from time to time.

1 - 2 the origin of zarchtons is highly

debated topic. some say zarcht-ons have evolved from fishes and some say they we're originally land creatures that have moved to live partially in water. some-times zarchtons are seen far in the open sea and they are often mistak-en for mermaids.

being amphibious creatures, zarch-tons have both lungs and gills, so they can breath air and in water. zarchtons have primitive culture system and they make use of resources from the sea to create clothing and accessories from shellfishes and other small crea-tures they hunt.

swimming in water and walking on land have developed zarchtons' leg muscles to enable them to take long leaps to help them hunt their prey and attack any one coming to their territory.

a busy place that operates every hour
of every day. large ships from ormund
harbardar port balabar and mysteri-
ous faraway lands to the east are
always found anchored or docked here.
xafian ships regularly take travel-
ers on board to south but the trip
can be very expensive unless you have a
writ from the king or the council

the great market of nothampton has
an endless supply of exotic spices.
clothes and luxury items from all
over the known world. the place is
also full of pickpocketers. the prices

May suggest a connection between Mount Grimrock and the Isle of Nex. The second-last paragraph provides a guide, using the Lexiconary code, for digging up the Undying One in the Barren Desert. "The one who knows you have been lied to" refers to one of the Stone Philosophers there. [3][4]
