The Mask and The Shadow

Arlin, once a master assassin, is now looking for a way out. He was always told there was only one way out , but he believes he has stumbled upon a way that won’t require him to stop breathing.
A Mask that is rumored to be a magical artifact gifted to the Baron of Olber by the queen of the Elves, to end the Elvish War is highly sought after by the current Shadow( leader of the Assassins Guild). Arlin must steal the mask to secure his freedom.
Aliandia, once an elven Princess, now fallen into disgrace, seeks the hated mask that her father made. She must destroy the mask that has brought her family shame and regain her standing with the queen.

One seeks a way out, one seeks a way back in. Will either get what they desire?
