WHy weren't FRCS dragons wiped out by the spellplague?

[coyote6]

Since 4e dragons appear to be (at least mostly) losing their spellcasting abilities (they'll have magical powers, but they won't be spellcasters, IIRC), I'd guess that the (surviving) dragons somehow divest themselves of their sorcery as a way to survive.

Perhaps as everything starts dying from the Spellplague, the smartest dragons notice that the higher-than-normal numbers of young dragons (that the above posters mentioned) aren't as seriously affected by the Spellplague as older dragons. Those smart old dragons deduce it is because the wyrmlings hadn't come into their sorcerous might yet, and figure out a way to shed their own sorcery. Lots of them do so; some don't, and die. With the higher starting population, dragons might end up more, less, or as common as previous, albeit with different abilities.

(Of course, I'm sure a few dragons will get written up -- by designers or individual GMs -- with additional wizard/sorcerer/warlock/whatever powers, rituals, or the like; those dragons will have done like other spellcasters, and adapted to the new rules of magic.)

Some probably did die, others were probably plaguechanged, and some might have just gone crazy. The Spellplague didn't kill everything magical. It was a plague. Some people/creatures got infected with it, others were mercifully not touched.

Why weren't the FRCS dragons all wiped out by the spellplague?

Same reasons why people survived the Black Death, despite some areas suffering a 90% death rate.
