Creature Type. You are a fey. You are also considered a goblinoid for any prerequisite or effect that requires you to be a goblinoid.

Fey Ancestry: You have advantage on saving throws you make to avoid or end the charmed condition on yourself.

Nimble Movement. Your tail and legs give you different movement options not available to other goblinoids. You have a climbing speed equal to your walking speed and are not affected by non-magical difficult terrain.

Light and Darkness:

The gift of the Queen of the Unseelie and the ever-changing nature of the Otherworld make your form and abilities shift like many of the Faie. Your change depends on whether you stand in bright light or darkness.

While in Bright Light:

Fury of Air. Light and Air guide your weapon, helping you strike true. When you damage a creature with a weapon attack, you may reroll one damage die and you must take the second roll. Your uses of this ability are equal to your proficiency bonus.

Eyes Unclouded. You have advantage on all checks to see through illusions or recognize them as such.

While in Darkness:

Fury of Darkness. Dark and Shadow cloak your form, helping you disappear after a strike. When you make a melee, ranged, or spell attack against a creature, you can immediately afterwards take the Disengage or Hide action as a Bonus action.

Eyes Shadowed. You can see normally in darkness, both magical and nonmagical, to a distance of 30 feet, and you do not have disadvantage on Wisdom (Perception) checks that rely on sight while in dim light.

While in dim light, choose either Fury of Air or Fury of Shadow, and either Eyes Unclouded or Eyes Shadowed.
