Design Commentary
As with the dwarves, Hatred and (especially) Defensive Training simply didn't seem to fit the history of the gnomes. Although they fought battles against goblinoids (and maybe kobolds) the humans from Galifar had the biggest impact on their society. But still, the gnomes managed to save themselves "without spilling a single drop of blood".

To address the gnomes' diplomatic abilities, I dropped both Hatred and Defensive Training for Specialized ability adjustments and the Emissary trait and changed the Keen Senses trait to Social Senses, which seemed more fitting as the gnomes are living in a society of constant plots and intrigues.

Finally, I added Knowledge to the Obsessive trait as it fits the concept and is simply a combination of Obsessive and the alternate Academician trait (see Advanced Player's Guide), and made this skill an automatic class skill.
