WARNING: The following post contains spoilers for the novel Stormrage by Richard A. Knaak. Readers still in the middle of the novel may want to veer away from this post, as I'll be discussing events covered over the course of the book.
Now that we've established what happened to Tyrande and Malfurion (in the midst of wibbly-wobbly timey-wimey ... stuff), we can begin to pick apart what happened in between the Sundering, the Third War, and present day. Tyrande Whisperwind is currently leading the night elves along with Archdruid Fandral Staghelm -- and Staghelm has a history that also stretches back thousands of years, one that's led him to his current less-than-friendly leadership.
Fandral Staghelm was born about 1,000 years after the Sundering and studied the druidic arts under Malfurion Stormrage, soon rising in ranks and becoming one of Malfurion's top lieutenants as well as training many of the new Druids of the Wild. Where Malfurion was even-tempered and kind, Fandral was hotheaded and aggressive, frequently clashing with Malfurion, and nowadays Tyrande over how night elf society should be run. He holds many strong beliefs that echo the beliefs of ancient night elves, including the belief that night elves are the supreme race on the planet, all other races are inferior, and night elves are the only "true" druids. Charming, isn't he?
