Rhyad is a trade city I made up and a lot of the RPers including myself have stopped there before continuing to Bervenia. It's big/important enough to house an airport for trade (maybe travel).

Tominas wanted it to be NW of Zidel as close to Vraweth's borders and I presume this is because he'd want his dagger back and for travel purposes.

I don't particularly care where it is but we can put it NW as Tominas stated. I don't think anyone else raised any concerns about it's location. 

Pila could be something important but it was a coastal port city. It's quarantined by Zidel at the moment

GM's call is final but maybe something like this?
