The Maskmaker is a mysterious entity residing in the darkest corners of the Gaiety of Visage. Do not bring light with you if you wish to face them.
They produce and sell masks for visitors and inhabitants of the hamlet; their wares include all Common and Uncommon masks. The Maskmaker seems to be able to read people's emotions and feelings - be they surface-level or deeper, quick to pass or character-defining - and they use this ability to craft the most suitable masks.
It was first encountered during the quest All Work and No Play. It often addresses others using the words 'visage of [insert emotion]'.
