Stonehenge in Shadowrun, What does "Background Count" mean? Options

[Foreigner]

Quick question, chummers:

According to The Sixth World website (http://www.divnull.com/lward/sixthworld/), Stonehenge, England has a Background Count of 4 (verified by MAGIC IN THE SHADOWS, page 84).


I'm only asking because I'm considering Stonehenge as a possible birthplace for my character in Sahandrian's campaign (essentially, he's an Immortal human descendant of an Immortal Elf although, as far as is known, it isn't any of the previously documented ones). I figure he's between 200 and 300 years old ([/I]i.e.,[/I] born approximately 1750--1850), but he doesn't look older than 25 or so.

I'm playing him as an Adept of the Magician's Way (Hermetic) (SR3 terminology--that's a Physical Magician, if you're still playing SR1 or SR2).

My question is as follows--would being conceived or born near Stonehenge have any effect upon the manifestation of his magical potential? That is, would he be BORN an Adept, or would the powers be latent, only to emerge at puberty or with training, as seems to be the usual case in SHADOWRUN?

As always, thanks in advance for any comments.
