The Lady of Glass

The Lady of Glass, Satheta, is a fey of crystalline perfection, cold calculation, and razor-sharp elegance. Ruling over the Mirrorwood, a domain of shimmering glass forests and endless reflections, she embodies both beauty and cruelty. A master of deception, manipulation, and unbreakable order, she offers her power to those who prove themselves worthy, binding them in a contract as unyielding and sharp as the glass she commands. Her warlocks are her enforcers, using her gifts to slice through illusion, command reflections, and ensure that all debts are paid.

Most pacts that are made with the Lady of Glass are done under layers of manipulation by this archfey. Many warlocks are unaware of what they have gotten themselves into until it is far too late. This archfey's cruelty does not stop at her enemies, her followers and warlocks, are often used as her play things for her own entertainment.

Shards of the Mirror

Starting at 1st level, your patron bestows upon you the ability to manifest razor-thin shards of glass to defend yourself and strike your foes. Whenever a creature hits you with a melee attack, you can use your reaction to cause a shard of enchanted glass to lash out. The attacker takes slashing damage equal to your Charisma modifier (minimum of 1).

Once you use this feature, you can’t use it again until you finish a short or long rest.

Gaze of the Glass Queen

Starting at 6th level, you can see through deception and make others behold their own weaknesses. You gain advantage on Insight and Perception checks against creatures trying to deceive you.

Shattered Form

Beginning at 10th level, you learn to fracture your own form like a broken mirror, making it nearly impossible to strike you down. As a reaction when you take damage, you can shatter into a thousand glass fragments, teleporting up to 30 feet to an unoccupied space you can see. Until the start of your next turn, you become semi-transparent and refracted, granting attacks against you disadvantage.

Once you use this feature, you must finish a short or long rest before you can use it again.

Queen of the Mirrorwood

Starting at 14th level, Satheta’s power fully envelops you, allowing you to command mirrors and reflections as if they were your own domain. You gain the following abilities:

• Perfect Refraction. You can cast Mirror Image at will, without expending a spell slot.
  
  
• Step Through the Looking Glass. As an action, you can step into any reflective surface (such as a mirror, polished metal, or still water) and emerge from another reflective surface within 1 mile that you have seen before. Once you use this ability, you can’t do so again until you finish a long rest.
  
  
• Glass Cage. You can use your action to conjure a prismatic glass prison around a creature within 60 feet. The target must make a Dexterity saving throw against your warlock spell save DC. On a failed save, they are trapped inside a transparent crystalline prison (as if affected by the Forcecage spell) for 1 minute. While inside, the target takes 3d8 slashing damage at the start of each of its turns. You can use this ability once per long rest.
