Eladrin and Elves
D&D 4e has 3 separate elven races, the eladrin, elves, and drow. Pathfinder, however, has no Eladrin. While playing with Pathfinder rules, there are a few ways to handle this. The standard Elven race can be applied to both elves and eladrin, so no changes are needed. The player can just roleplay them separately.
Another option is to use one of the custom made Eladrin races for Pathfinder found on the internet. Blood Elf builds from World of Warcraft inspired classes may be allowed as well.
As no players have decided to use a High Elf, or Eladrin yet, no official ruling has been made yet. But while playing under Pathfinder rules, Eladrin will be referred to as High Elves or Desert Elves.
