Laurance because remember how he always said "I will protect you" and Esmund is the Protector.

Protected Aphmau from Garroth

Garroth on the other hand can also be Esmund for he was Aphmau's first guard and he proved that he was Aphmau's protector.

Protected Aphmau from Zane

Aaron can also be the Protector because he saved Aphmau (I think he can be Esmund)

Protected everyone from Zane's hands?? (More like saved)
