[@agentmanatee] It's one of those suspense of disbelief things. IIRC there weren't any serious casualties in either grand melee described in the books. Injuries yes, but no notable characters are noted as dying in either occasion. Of course there can be some deaths in our melee but for the sake of game progression let's avoid the deaths of PCs and important NPCs ie notable warriors and scions of noble houses. 

[@Abefroeman] When the Dothraki send their people they're not sending their best. 

There's honestly no firm defined method to hatch a dragon egg without committing a blood sacrifice as far as I can see, but presumably the Targs had one. But Aerion is the blood of the dragon so it should be possible for him to hatch an egg and ride a dragon, but that would definitely create a splash. 

I'll have something late tonight or tomorrow.
