Assume, there is an accident having taken place in a city.

The accident has been described, the people involved have been described, the city too, and then I want to say "far from them (from the accident and the people involved), there is a location".

Because, I *need* to continue the story by saying "at *that* location something else happened".

In this context, would the {chaHDaq Hopbogh Daq tu'lu'} be adequate for "far from them (the people involved), there was a location" , so then I will say {DaqvamDaq qaS ..} ?

Perhaps, I can just say {Daq HopDaq qaS...}.

But suppose that in the story, there is someone else involved too, who may not be near enough to the accident, so I *need* to specify near to *who* the location to be described next, actually is.

I'm not fully following you, but I don't think I need to. Hop is far from whatever the speaker, writer, listener, reader understand it to be from. Make it clear what it is far from, then say it's Hop.

It would be a lot easier if you would just give us what you're working on, with the surrounding text for context.
