Breeds native to the British Isles-Common breeds-Relation to Continental breeds-The effect
of modern diet upon size-Heredity of Regal Copper-Venomous and Vitriolic breeds .

...  IT  IS  AS  well  to  recollect  that  Yellow  Reapers,  so  often  unjustly  regarded  with  that
contempt  engendered  by  familiarity,  are  to  be  found  everywhere  because  of  their  many
excellent qualities: generally hardy and not fastidious in their diet, untroubled by all but the
worst  extremes  of  heat  or  cold,  almost  invariably  good-humoured  in  character,  they  have
contributed  to  almost  every  bloodline  in  these  Isles.  These  dragons  fall  squarely into  the
middle-weight  range,  though  they  range  more  widely  within  the  breed  than  most,  from  a
weight of some 10 tonnes to as many as 17, in a recent large specimen. Ordinarily they fall
between  12  and  15  tonnes,  with  a  length  generally  of  50  feet,  and  a nicely  proportioned
wingspan of 80 feet.

Malachite  Reapers  are  most  easily  distinguished  from  their  more  common  cousins  by
colouration: while Yellow Reapers are mottled yellow, sometimes with white tiger-striping
along  their  sides  and  wings,  Malachite  Reapers  are  a  more  muted  yellow-brown  with  pale
green  markings.  They  are  generally  believed  to  be  the  result  of  unguided  interbreeding
during  the  Anglo-Saxon  conquests  between  Yellow  Reapers  and  Scandinavian  Lindorms.
Preferring cooler climes, they are generally to be found in north-eastern Scotland.

From hunting records and bone collections, we know that the Grey Widowmaker breed was
once  very  nearly  as  common  as  the  Reapers,  though  now  they  are  rarely  to  be  found;  this
breed being so violently intractable and given to stealing domesticated cattle has been made
nearly  extinct  through  hunting,  though  some  individuals  may  be  found  living  wild  even  to
this day in isolated mountainous regions, particularly in Scotland, and a few more have been
coaxed into breeding grounds to preserve as basic  stock. They  are small and aggressive by
nature,  rarely  exceeding  8  tonnes,  and  their  colouration  of  mottled  grey  is  ideal  for
concealment  while  flying,  which  inspired  their  cross-breeding  with  the  more  even-tempered Winchesters to produce the Greyling breed.

The  most  common  French  breeds,  the  Pêcheur-Couronné  and  Pêcheur-Rayé,  are  more
closely  related  to  the  Widowmaker  breed  than  to  the  Reapers,  if  we  may  judge  by  wing
conformation and the structure of the breast-bone, which in both breeds is keeled and fused
with  the  clavicle.  This  anatomical  peculiarity  renders  them  both  more  useful  for  breeding
down into light-combat and courier breeds, rather than into heavy-combat breeds...

Cross-breeding  with  Continental  species  is  also the  source  of  all  the  heavy-weight  breeds
now to be found in Britain, none of which can be considered properly native to our shores.
Most  likely  this  is  due  to  climate:  heavier  dragons  greatly  prefer  warm  environs,  where
their  air-sacs  can  more  easily  compensate  for  their  tremendous  weight.  It  has  been
suggested  that  the  British  Isles  cannot  support  herds  vast  enough  to  sustain  the  largest
breeds; the flaws to this chain of reasoning may be shown by consideration of the very wide
variations in diet to be tolerated among dragons insofar as quantity is concerned.

In  the  wild,  it  is  well  known,  dragons  eat  so  infrequently  as  once  every  two  weeks,
particularly in summer when they prefer to sleep a great deal and their natural prey are at
their fattest; it will then come as no surprise to learn that dragons in the wild do not begin
to approach the sizes which can  be found among their domesticated cousins, fed daily and
188
more, particularly during the early years so critical to growth.

By  way  of  example  we  have  only  to  consider  the  barren  desert  regions  of  Almería  in  the
south-east  of  Spain,  scantly  inhabited  by  goats,  which  are  the  native  grounds  of  the  fierce
Cauchador Real, part ancestor of our own Regal Copper; in domestication this breed reaches
a  fighting  weight  of  some  25  tonnes,  but  in  the  wild  is  scarcely  to  be  found  over  10  or  12
tonnes...

The Regal Copper exceeds in size all other breeds presently known, reaching in maturity as
many  as  50  tonnes  in  weight  and  120  feet  in  length.  They  are  dramatic  in  colour,  shading
from red to yellow with much variation between individuals. The male of the species is on
the average slightly smaller than the female and develops forehead horns in maturity; both
sexes  have  a  marked  spiny  column  along  the  back,  which  renders them  particularly
hazardous targets for boarding operations.

These great beasts are unquestionably the greatest triumph of the British breeding grounds,
the  product  of  some  ten  generations'  labour  and  careful  cross-breeding,  and  illustrative  of
the unanticipated benefits which may be yielded by matings not perhaps of obvious value. It
was  Roger  Bacon  who  first  proposed  the  notion  of  breeding  females  of  the  smaller  Bright
Copper  species  to  the  great  sire  Conquistador,  brought  to  England  as  part  of  the  dowry of
Eleanor of Castile. Though his suggestions were founded in the erroneous supposition of the
time,  which  thought  colour  to  be  indicative  of  some  elemental  influence,  and  the  shared
orange  colour  of  the  two  breeds  a  sign  of  underlying  congruence,  the  cross  was  a  fruitful
one,  leading  to  offspring  even  larger  than  their  prodigious  sire,  and  better  able  to  sustain
flight over distance.

Mr. Josiah Colquhoun of Glasgow has suggested that the disproportionate size of the air-sacs
of  the  Bright  Copper,  relative  to  their  frame,  properly  deserves  the  credit  for  this  success,
and it is certain that Regal Coppers share this trait of their female progenitors. M. Cuvier's
anatomical  studies  suggest  that  indeed  the  vast  bulk  of  the  Regal  Copper  would  crush  the
very  breath  out  of  the  dragons'  lungs,  if  unsupported  by  aught  but  their  surprisingly
delicate skeletal systems...

While  no  pyrogenic  species  are  to  be  found  in  the  British  Isles,  despite  many  attempts  on
the part of our breeders to induce this most valuable trait, so deadly to our shipping in the
persons  of  the  French  Flamme-de-Gloire  and  the  Spanish  Flecha-del-Fuego,  the  native
Sharpspitter  breed  is  notable  for  producing  a  venom  to  incapacitate  its  prey.  Though  the
Sharpspitter itself is too small and low-flying to be of great value as a fighting beast, cross-breeding  with  the  French  Honneur-d'Or,  for  size,  and  with  the  Russian  Ironwing,  another
venomous  species,  yielded  several  valuable  crosses:  better  fliers,  middle-weight  in  size,
with more potent venom.

Interbreeding  among  these,  with  frequent  infusions  from  the  parent  breeds,  culminated  in
the successful hatching of the first dragon which can properly be termed a Longwing, during
the  reign  of  Henry  VII.  In  this  breed,  the  venom  had  become  so  potent  as  to  be  more
properly termed acid, and of a strength which could be turned not only against other beasts,
but  against  targets  upon  the  ground.  The  only  other  truly  vitriolic  breeds  known  to  us  at
present are the Copacati, an Incan breed, and the Ka-Riu of Japan .

Longwings  are  unfortunately  instantly  identifiable  upon  the  battlefield  and  impossible  to
189
decoy, due to the unusual proportions for which they are named; though they rarely exceed
60  feet  in  length,  wingspans  of  120  feet  are  not  uncommon  among  them,  and their  wing
colouration  is  particularly  dramatic,  shading  from  blue  to  orange,  with  vivid  black-and-white striations at the rims. They possess the same yellow-orange eyes as their progenitor
the  Sharpspitter,  which  are  exceptionally  good.  Though  the  breed  was  first  considered
intractable, and indeed some consideration was given to their destruction, as too dangerous
to  be  left  unharnessed,  during  the  reign  of  Elizabeth  I  new  methods  of  harnessing  were
developed  which  secured  the  general  domestication  of  the  breed,  and  they  were
instrumental in the destruction of the Armada...
