Blazing Spark - The end of days

I laid there, on the hard ground, weak and defeated. Cipher’s dark bodiless form surrounded me, encasing me in a cocoon of thick black empty smoke. “You’ve lost Blazing Spark” the dark entity’s voice lulled at me from all directions. I had stopped struggling long ago, my hooves were torn and bloody and my coat was covered in dirt. I let my mind wonder as the darkness enclosed me further, I wondered of how this all started. It’s funny, how only a few days ago I was a normal magical and supernatural consultant living from the measly pay I got from working with the royal guard of Canterlot, and now, this. The darkness grew closer and I felt myself begin to slip into it, into oblivion; a distant maniacal laugh floated through the air.
My mind wondered again, how did this start? Oh yes, with a letter.
