A thought on England, I've been thinking to much... Options

[Ophis]

Okay, I've been running a game based in my home nation and I've been thinking a bit.

Okay Britain has it's magical weirdnesses and all most notably one of the more beefy power line systems in the world (it and the ring of ire are the ones that seem to get mentioned.) Dragons seem to have a large scale interest in sites of power in general and power lines in particular (okay the asian dragon lines may be a special case on that).
However despite this the Welsh Greats (Rhonabwy, Celedyr and the Sea Dragon) seem to have little interest in England. Celedyr has holdings in Scotland and Wales (Transys' major areas Caerleon and Silicon glen), but nothing of note in England. Even SKs presence seems minimal. Why is this? Does it have anything to do with St George Englands patron saint and a notable dragonslayer? Given the lack of reptilian awakened in Tir Nan Og the patron saint myths seem to have some sort basis in fact. That was the first odd thought.

The second is probably odder. By some references in SR material Harlequin was Richard the Lionheart. Fine and dandy you say, but says I one of the more notable characteristics on Richard was a tendency to be out of England as much as he can be during his reign. Again I ask why. What is it about England that means that Dragons and Immortal elves are shall we say discouraged from spending time in England, given some suppositions about the origins of Immortal elves (dragon blood) I'm inclined to say England is guarded against Dragons.

Simply put I'm looking for any ideas as to who, what and why.
