In the end of Orc Scouts' aq, I found some interesting stuffs buried in a
hidden location:
Some food
An empty piggy bank
Some baseball cards
Some comic books
A mouldy book binder

When I type 'read binder', it prompts: You run your finger across the surface
of the book, incidentally smearing several of the worms squirming on the rotten
cover, and you think you can detect the characters: "K????????
A????????i??."
The weird thing is these characters change each time I read it. So I tested a
few time, here's the result:
K???????? A????????i??.
9ita? ?????.
Kitab A??Azif.
?t??????????? ped ??z?f.
??n????a ?l ?????????.
K?a?? ?l?????????????????????.
??i???? ?? A??f.

?i?????? ?? ????z??????.
????????b?Al?Az??l.
???t?????Vrlc??z???f.
K????b ?l??Az??f.
K???tab?????l???i?.

It is easy to find some patterns:
1 The first word starts with K and ends with ab
2 The last word ends with if or zif
3 There is a capital A in the middle of these characters

So after some searching, I found a book matching these patterns:
Kitab Al-Azif, the original Arabic Necronomicon (a fictional grimoire in
Cthulhu Mythos) http://fairfieldproject.wikidot.com/kitab-al-azif
I am 95% sure this book is the right answer.

BatMUD is AWESOME.

And those Orc Scouts are fucking terrifying now. Leave the little fuckers to
rot!
