Mongrel's Tooth and Consequences

Mercenary. Outsider. Mongrel.
That is how things were. That is how I liked things. Alone. Depending only on myself. No strings, no chains, free to act as I wish.
Recent events have changed my life, unfortunately. First, I could not refuse to help my family, especially my favorite cousin. Then for no sane reason, a past client stuck around to help me out.
I smell the hot metal of chains being forged, the restriction of ties knotting. My life will never be the same. It must be a hazard that comes through my family. The question is...
Which family line is causing me to go from mercenary to some kinda questing knight?
