I was a coward. I abandoned my sister in escaping Whitestone after the rest of our family was killed. After she risked herself to help me escape. She was trapped with those monsters for years and it is my fault she suffered. I should not have left her, even if it meant dying. Everything that happened to her is because I left her. I let a demon into my mind, even if it was unknowingly, and if things had gone differently, I could have killed everyone I care about. I unleashed these weapons on the world. They didn't exist before I made them and a horrible person learned from my work and is going to do awful things and I do not know how to stop it. I got Vex'ahlia killed and it does not matter that she was brought back. I am still responsible for what happened to her. I got our friend Grog killed because I thought I knew best. And it was fixed too, but it does not change anything. Things being fixed does not change that they happened. And I know I will continue to do things that hurt people because I am broken and I have always been broken. So I do not think I am being too hard on myself at all.
In some circumstances, the less good get them killed.
Dragons are very real from our standpoint. There are several we are currently trying to defeat.
