Half-Elves
Half-Elves are a side effect of the many millennia of warfare between Humans and Elves. The winning side takes captives and/or slaves and then takes advantage of the opportunity. Elves think of anyone with even one Human ancestor as a Half-Elf, and anyone with more Human ancestors than Elven as Human. Humans see anyone with even one Elven ancestor as Half-Human, and anyone with more Elven ancestors than Human as an Elf. Which category any one character actually fits into is between the player and the DM. A Half-Elf's biggest racial problem outside of Bifure is being mistaken for a Mer. Bayside has a large population of Half-Elves.
What Humans or Elves can speak, so can Half-Elves.
Half-Elves, being not completely human, get to multiply their Wild Talent chance by three before rolling it.
