When The Blackbird Whistles

I have been given a mission. Find the Blackbird.
To find Philip Hakorn, the leader of the Blackbird warrior guild, who was taken from his home. I have just retired as the first Minister of Pranda and was looking forward to my retirement. Riding around Tralia risking my life was not my first choice once released from duty. But this search leads me from my old training ground, down to the southern forest and into one of the river towns that holds more secrets than I thought possible. We must find my friend at all cost.
There was more to this than an abduction. Someone searched for the guild members kidnapping or murdering them. What were they searching for? What did Philip know that he became a target?
The Blackbird warriors were all summoned and when The Blackbird whistles all listen and obey.
