“ Command me, and I will silence her forever.

Shadow Sister Cookie (Korean: 그림자사제맛 쿠키, geulimjasaje-mat kuki, "Shadow Priest Cookie") is an NPC introduced in the Tiers of Chaos update (v1.4). This Cookie is a nun of the St. Pastry Order and answers to Reverend Mother Cookie.
Personality[]
Shadow Sister Cookie is a devout follower of the order that 
Pastry Cookie also follows, presumably being a rank higher than Pastry Cookie's. Being a more loyal follower of St. Pastry Order, the Cookie commits to silencing any possible threats to the Order—including threats that come from members of the Order itself.
Story[]
Shadow Sister Cookie first appears during the last section of the Tower of Sweet Chaos campaign. The Cookie appears after Pastry Cookie and Reverend Mother Cookie speak about the events that had occurred just before at the Tower of Sweet Chaos. Shadow Sister Cookie addresses Reverend Mother Cookie, calling the Cookie too merciful and asking for permission to eliminate Pastry Cookie. Reverend Mother Cookie refuses, stating that there is nothing to worry about and that Pastry Cookie is a "very loyal student." As revealed by Reverend Mother Cookie, Shadow Sister Cookie also guards the secrets of the Tower.
Shadow Sister Cookie later makes an appearance at the end of Day 5 of the Cookie Odyssey (Chapter 1) story as Mysterious Shadow 1, talking to and informing Mysterious Shadow 2 about the departure of the vessel that carries the Soul Jams from the Vanilla Kingdom to the Crème Republic. The Cookie is then seen with Missionary Cookie exchanging details about the current situation.
