It's a trick question, Aquilla. A Mask is not made.....

“ It's a trick question, Aquilla. A Mask is not made. She is remade. First she is destroyed. Stripped down to the trembling child that lives at her core. It doesn't matter how strong she thinks she is. Blackcliff diminishes, humiliates, and humbles her." "But if she survives, she is reborn. She rises from the shadow world of failure and despair so that she might become as fearful as that which destroyed her. So that she might know darkness and use it as her scim and shield in her mission to serve the Empire. ”
