btw...there is no 'Heron Guard King'.
1) Alric is an Emperor, all the other leaders of the Empire have been Emperors.
2) 'Heron Guard King' is like saying something like 'Navy Seals' President', its redundant, all Heron Guards serve Alric, it's in their definition.
3) Heron Guards don't have an individual king, the emperor they serve is the same one as the leader of the entire emperor. Also, if you took it another way, a king could not be a heron guard, because they're sworn to military service under the Emperor.
just semantics...call yourself whatever you want.
