Fale is a character that lives in Aurora Village and gives multiple quests to Dust if the player chooses to speak with him.
Fale supplies the Watchmen and is the reason for the guard's poor armour and weapon design as Fidget states. Fale assigns the following quests: Better than Nothing, Taking Point, Slimed, Reinforcement, Freedom of Movement, and Find the Sparklies. Doing all these quests gives the player the Achievement: "Opposite of Fail" which is a pun on Fale's name.
Even though Dust completes the quests, the guards won't mention anything about it.
Fale says he will buy the material at a higher price than a merchant, which is true as he pays more for it than if Dust were to sell the material to Sereth or Mordecai.
