The Twilight Sovereign

You made a pact with a powerful entity who commands the powers of the Twilight Realm. Pacts made with patrons like the rightful rules of the Twili, such as Queen Midna, are made with the understanding of protecting the Hyrule and the rest of the mortal world from the dangers of the Twilight Ream. Patrons such as the Usurper King Zant, however, aggressively recruit warlocks, granting them the powers of the Twilight Realm to further their schemes.

Beast of the Sovereign

At 1st level, you can turn into a bestial form as a Bonus Action. Select a Beast with a Challenge Rating of ¼ or less; you turn into that creature’s form, gaining its statistics, though you retain your Hit Points, Intelligence, Wisdom and Charisma. You gain the Beast’s skills (also retaining your own), along with its senses. You can understand languages as normal, but cannot speak, nor can you cast spells. While in Beast form, you gain Darkvision of 60 feet (or improve your natural Darkvision by 30 feet).

Twili Trickery

At 6th level, you can use the Twilight power to protect yourself, using your Reaction when you are targeted by an Attack or Spell Attack (you cannot use this ability against area-of-effects, or against attacks you are unaware of). The attacker must make a Dexterity Saving throw against your Warlock Spell Save DC; if they fail, the shadows rise up between you and the attacker, creating a small portal that the attack falls through. A second portal instantly opens at any point within 30 feet of you, ejecting the attack; you can cause the attack or spell to possibly hit a new target within range of that point, or have it just harmlessly miss you. If the attacker succeeds the Dexterity Saving throw, you instead take half damage and fail to open the second portal. If the attack has a new target, you must make an attack roll, using your spell modifier. You can use this feature an amount of times equal to your proficiency bonus, you regain all charges upon finishing a long rest.

Twilight Portals

Beginning at 10th level, you can use the Twilight Portals to move great distances. Mechanically, this feature functions identically to Teleportation Circle, though it only functions with Twilight Portal Destinations. You can open a Twilight Portal by completing a minute long ritual, after which you cannot do so again until you’ve finished a Long Rest.
When you gain this feature, you choose two locations that you know very well and have free access to; you gain both locations as Twilight Portal Destinations. You can learn the coordinates of other Twilight Portals, either on your own or from other Twilight Sovereign Warlocks. At the GM’s approval, you can also spend 500 gold and 8 hours on a ritual to create a new portal for use- however, only certain areas where the barrier between Hyrule and the Twilight Realm is thin are suitable. If you slay a creature with Lair Actions in its lair, you may forgo the ritual, though you still must sacrifice 500 gp worth of treasure, to establish a twili portal over the Lair or at its entrance.

Guest of the Sovereign

At 14th level, your Sovereign has granted you a portion of their realm as your own, making you something of a baron in their court. You may cast Magnificent Mansion, without needing Material Components and without expending a spell slot - after casting it the first time, the mansion is always the same shape and condition it was when you left it (though damage is repaired and stores are restocked). Your servants are all real Twili on your patron's payroll, not magical creations, and they come and go from the mansion to the Realm of Twilight, though your mansion always has a full staff. You can also send your servants to the Realm of Twilight to deliver messages or on specific tasks; they are friendly and loyal to you, though how to treat them may improve or harm your relationship. Once you use this feature, you must take a Short Rest before doing so again.
