She is a High Elf. I can find no reference to her being a dragon. She is the apprentice to a dragon though.
I haven’t seen any source linked to Chronicle that states they’re all light skinned, nor would I put my faith in Wowpedia or Wowwiki as both are not always canon sources unless you can find the source linked directly to what they’re saying.
While I may disagree, that is your choice. I’ll still support the thread.
