Update: I've just realized the image had a major flaw in it. I've added a new image and made sure it's correct. Nothing else has changed, only the image. Sorry for the inconvenience.
I have six words that all start with "a". Each word is specific to one of these six book series:
A Song of Ice and Fire
Harry Potter
His Dark Materials
Redwall
Sherlock Holmes
The Lord of the Rings
Each word occurs at least once in the canon of its respective series, but almost certainly never occurs in the canon of any of the other series. The words are not necessarily standard English.
This image encodes all six words. Can you figure out what they all are?
Hint:
Each of the secret words relates to one of these six words (given in random order):
changer healer teller river maimer treasure
Verification:
To verify your answer without asking me, put your six guessed words in the same order as their series are in above. Make them all lowercase and separate them with single spaces. e.g.
asoiafword hpword hdmword rword shword lotrword
Take the MD5 hash of this string. If you get 66a8a3195f64cb095da3643c7731c0f5
then you've got the answer exactly correct!
