The teams of TibiaSecrets.com and Tibiopedia.pl have combined their forces to explore all messages from NPCs. You can see their results on the Transcription Project page on TibiaSecrets, as well as on Tibiopedia, if you check out an NPC on their fansite. Take a look at the transcriptions of Emperor Kruzak, for example. 143 transcriptions have already been made, more will follow!
