Well Twilight is the area between night and day so...
I guess Twilight rules for those few minutes when its not really night, but the day isn't quite gone...
Sounds like a really easy job.
Oh and by the way I just discovered a Pony Blog similar to EQD only they deal mainly in grimdark material.
I don't know if you guys are into horror as much as I am so I'll just let you know that the name of the site is,
"The Tartarus Project"
and you can all google it I guess.
Its also very new apparently.
In the meantime here's one of the only pictures I felt comfortable sharing with you all from that site.
Alien for the win.
