Drelanim Whisperwind

All the wardens you see at Starfall Outpost are all named after the randomly generated names of hero units in WC3. In fact, Cordana Felsong, who you'd think would have been a brand new character with how important she is to the plot, is also one of those random heroes.

Drelanim Whisperwind accompanies Cordana Felsong to Frostfire Crag when Cordana sends you there for Vouchsafe Our Arrival, but she does not come along with Cordana and Khadgar when they continue to Throm'var during Safe Passage. Neither is she present at your garrison when Cordana sends you to Frostfire Ridge in the first place, nor does she turn up during the events in and around Throm'var.
It kind of makes you wonder where she is hiding while Cordana is waiting for you at your garrison, and why she does nothing but watch during the demon quest line.
Oh, and whether she is in any way related to Tyrande Whisperwind, of course.

There are six known Night Elves with the last name "Whisperwind." Kaldorei surnames are speculated to go back millennia of generations in a bloodline, so the following may or may not be distantly related.
