Often, when talking to an NPC, the player will receive a challenge scroll, puzzle box or light box that they must solve before receiving the next clue. Once the solution is found, the player can get their next clue by talking to that NPC. The solution of an anagram is always the name of an NPC. For example: orchestra is an anagram of carthorse.
An anagram is a string of letters, which can be rearranged into another word or phrase.
