1) the ED is being corrupted BY THE OLD GODS! NOT THE TWISTING NETHER!
2)grats..you read War of the Ancients 1,2 and 3 XD..lol sorry but youre WRONG! after 10k years he came back not to let sargeras enter the world,but to get an army to kill arthas and then fulfilling the job kiljaeden gave him..although the nagas actually just used illidan..play warcraft 3
AND NO! lady vashj is NOT their leader! azshara is..and azshara sent lady vashj to the ground to "aid" (use) illidan..although its not mentioned in warcraft 3 that she uses him...SHE DOES...and some of the highborne DID survive and never became the naga..but after 3k years they were banished (i wonder what happened to them for 3k years..)
sorry like i mentioned earlier i havent read any books or played warcraft 1 2 or 3
