Having read the Player's Guide, I have changed Piedro's background to cover his link to Professor Lorrimor.
[sblock=Background]Piedro's (born Sturm Cantero) father was a shift supervisor in the Mindspin copper mines. Growing up, Sturm came to hate the mines and was always arguing with his father, who wanted him to join him in the mines. After one particularly acrimonious argument Sturm decides that enough is enough and he will leave the mines and his family.
As it happens Professor Lorrimor just happens to be visiting the mines and Sturm asks him if he can accompany him to the nearest human town. The professor, always interested in unusual behaviour, is intrigue by a dwarf who hates been underground and agrees. Over the next few weeks the professor and the young dwarf spend their evening talking round the camp fire and the professor sees something in the young Piedro (as he now calls himself) and arranges for him to be trained by his personal scouts. Eventually the party arrives back in Ravengro, where the professor arranges for Piedro to complete his training with a party of undead hunters.[/sblock]
