Thoth, the ibis god of knowledge and writing, asks Kathrine
a riddle for her if she wants to enter his library of knowledge.
Therefor I've drawn Thoth as a statue instead of as a living god,
and speaks telepathic to those who enter his altar or temple that
hides the entrance to his secret library of knowledge and writings.

For the riddle, I use a movie quote from The Librarian, as it fits
with the egyptian theme of knowledge.
