Scars of the Past

"Why would you just walk in?" Asked the griffin as we walked through the dark tunnels. The tunnels looked much like what I thought a mine would look like. Wooden boards kept the walls from collapsing and dirt occasionally fell from the drilling.
"There was no other way to get in" I said.
"You are the Dusk Scar, right? You have the same silvery body and jet black mane." He said, trying to confirm his suspicions.
"Yeah." I said. It was true, but I never knew I had made a name for myself. I always tried to remain covert, but apparently that failed.
"Why would you come back, we were hunting you down." He said, flabbergasted. We continued to walk, but his steps began to get more and more hesitant as the tunnels got darker.
"I had to save her."
"You didn't owe her anything."
"I owe every honest mare, stallion and foal my life." I said angrily, but I knew he was right. They hadn't done anything for me.
"Why?"
I breathed heavily for a moment and we both stopped walking. "Because I see too much of her in everypony." I finally said
"Oh, this is about your marefriend."
"No, this is about me failing my sister. I swore I would always protect her... and I failed." We started walking again and the only sound was an occasional drip of water and our hoofsteps. I guess he doesn't have hooves, but his claws made a similiar noise, though it was sharper.
I imagined him licking his beak, preparing to say his next sentence. "I can get you out. I can hide you away until they forget about this."
"No, I don't need help. Take me to where they are holding the yellow Pegasus and make it easier for us to get out."
"Sure thing." He said. He took an immediate left turn, pulling my chain. I could feel the pressure raise, warping my hearing.
We came to a stop where a dim light came on. The light revealed multiple jail cells, all dirty from the grime, dried blood and other unidentifiable substances.
"I put her in the cleanest of cells, so you will get the one next to it. You need to dig you way underneath the bars to get into her cell. I'll turn on and off the light 4 times as a signal. I don't know when I will be able to get you out, but don't give up, that will make escape harder. If you have a level-head, the path out is easy, but if you don't, it becomes a maze. I'm not exaggerating, this tunnel is... ancient. I'm Damian by the way." He said, opening a cell door.
I gulped and walked into the cell. I feared for his life, the mare's life and my own. "See ya Damian." I said as the door was locked and the light turned out.
