Appearance[]
It is a sword with a grey to dark gradient to the blade. The middle features a silver striped guard with a gem in it. It also emits black 
Sparkles that will appear on the avatar while worn and equipped in-game.
Function[]
When in-game, the user can click once to swing the blade, or double click to Lunge and strike forward horizontally to their mouse/touch location. As an extra effect, while lunging with the sword, it will leave behind a trail of dark waves behind the blade.
Unique Ability - Lights Out[]
Pressing Q will cause the entire map to go black and the current time to turn night. However, a 45 stud radius from where the user activated it will still be illuminated by light. Upon activation, the user becomes invisible and has their speed set to 40 as well as hiding the sword. This effect lasts 15 seconds and goes on a 15-second cooldown. Uniquely among all periastrons, this periastron is able to use its ability even while lunging.
Tech Skill[]
Using Lights Out mid-air prevents the circle of light from reaching the ground, making it safer from revealing your location easily.
You can use Lights Out to instantly power Sword of Darkness' night-empowered state, its darkness ability can be used with Frost Blade to have a high chance of freezing the opponent.

Trivia[]

- This is the only periastron that can use its ability while lunging, this is because unlike most other gears, it only checks for whether the ability is off cooldown or active, this also means you can use the ability when you are dead (you have to have died while equipping noir though)
