Some races are not part of families.  They are so unique as to be metaraces
unto themselves.  In the case of the humans, their racial language is
shared by all save the Xodar who can understand but not speak the language.

In the case of the other races, their racial language is unique to their 
race.  The Eponymous races are: anakim, catfolk, devil, drensieq, dwarf, 
flynd, gnome, kanku, kizanki, kreen, and valkyrie.
