I had the strangest urge to draw Thanatos, the alicorn charged with the domain of death and the afterlife in my AU, the literal pale horse.
 
The first among the World Scribe’s creations, and destined to be the last. After all, someone has to put the chairs on the table and switch the lights off when it’s time to close. A permanently sleep deprived looking stallion who was the first to see all living creatures as they are made, and the last to see them as their time runs short, always punctual, arriving just in time to speak praises of a life well spent however small, and to greet the recently deceased as an old friend might. He is one of the few remaining wardens of Tartarus, and keeper of the Elysian Fields where those who have nothing left to learn upon the mortal plane are allowed to ascend, others being sent back to reincarnate until a time at which they may walk into such a paradise.
