I just finished the azure dragon quest line in azsuna and something khadgar says confused me.
When you reach senegosa and find out that hes gravely wpunded khadgar says something like "we must save him, for all we know hes the oldest living dragon on azeroth".
Older than the 5 aspects created by the titans? Maybe my qow lore is alittle rusty but how can he be the oldest living dragon if 3 of the original 5 aspects still live?
