Arnold Blair was the father of Christopher Blair and husband of Devi Soulsong. A Terran Confederation war hero during the Pilgrim Wars, Arnold met and fell in love with Devi, a pilgrim. During the end of the Pilgrim Wars, Devi was caught on Peron and Arnold attempted to rescue her, leaving behind his 3 year old son with his sister Jennifer. Eventually, Arnold and Devi were killed during the Peron massacre.
To the general populace, Confed propaganda celebrated Arnold Blair as a war hero. It was years later the truth was discovered which caused a deal of grievance to the young Christopher.
Prior to his death, Arnold designed the Merlin personal digital assistant based on his own genetic template. In his holographic appearances, Merlin would appear as a long haired version of Arnold Blair.
