The Diary

The Diary is an item found by Tara and Terhal, in a secret cave under the farmlands of Ba Sing Se. It contains lists of Air Nomad artefacts, and potential sites for their recovery. Interestingly, the author has been using the diary to track the movements of some of the artefacts; they are spread to the Four Nations.

Of particular interest is a list headed up "Wan Shi Tong's Library"...

The Author
The person who originally owned the diary seems to be a collector of some sorts. It is likely that he works for the Dai Li, the secret police of the Earth City Ba Sing Se.

The Symbols
The final page contains a conundrum - the Dai Li symbol seems to be composed of other symbols...

For those who look with a magnifying glass, the symbols of the White Lotus and Hollow Circle appear. The Hollow circle appears to be bleeding onto the White Lotus...
