[@Crimson Raven]Easily(oh, and to address your earlier question, yeah, that makes sense. Aether her is basically the same as holy or light magic in some magic system), he just has to take it easy for a bit and eat a person or two. Only problem is Phelegthon, since Joshua has made such a nig deal about the guy hunting Nidhogg down and annihilating him, it would be a bit out of character to have the guy be all "Oh, there he goes. Darn, I'll get him next time." Something I was planning, however, was that Nidhogg shifts his body to change the appearance, steals some clothes from on off the dead bodies in the building that just got brought down(because this is a populated city and in a situation like this, most people would hunker down in nearby buildings and hope shit blows over) before completely suppressing his power, making it seem like he died/escaped. This would also have the side effect of suddenly thrusting Jackson into the world for an indeterminate amount of time, so that would've been fun. 

Does this seem like a plausible, if risky, escape plan?

I'm pretty sure that the area would be evacuated. After all, who would want to be in a nearby building while mages dueled? Wasn't there something at the beginning about people fleeing?

As for Nidhogg, he could kill someone...

"...and wear their body as his own..." (Get the reference?)
