Knowing whom your Realm is named after - Who is Dath'Remar?

This post was actually inspired by Rioriel because I noticed he did a postcard on Khadgar.  I recall when our guild was on Khadgar and in BC, Khadgar was there in Shattrath we were all like ooooooh is that who our realm is named after!  So I realised today that I had no idea who or what our realm, Dath'remar, was named after.

This is The Shrine of Dath'Remar in Eversong Woods.  Here is what the plaque at the bottom of the monument says:

Dath'remar Sunstrider was the first high King of Quel'thalas.  He was the leader of the Highborne who survived the War of the Ancients.  You can read more in WoWWiki here.
