!!!Your final test!!!

This will require a knowledge of all HUMAN knowledge.


First:

Only one human legion speaks a true word
Although he blends in with the rest
True to the rules

Which is he?


Second:

Alice:
"Let me see: four times five is twelve,
and four times six is thirteen-
and four times seven is-- oh dear!
I shall never get to twenty at that rate!"

Based on Adams Answer (you know, hitchiker's radix)
Alice knew she couldnt get to defcon XX!
Four times thirteen gave what instead
Knowing of course Alice fills with numbers first
Lowers second then uppers
Hint hitchers ultimate answer is ten to Alice here

Take the answer to one in radix 10, tack on the end the answer to two in the Adam's Radix,
and use that as your final code word.
