(Back at last... Will be gone again August 1 - 14, however, although I may be able to sprig up internet access at that time. Email me if you want to work out a way to leave Nathaniel behind during that period, if you don't want to autopilot -- I'm happy with your job, but as a DM I know it can be that-much-more to worry about.
As far as emails, my account was down shortly -- try again, but tell me if it's still not working.)

Which is not to say unnatural: But perhaps there is something special in the air, only there once every few hundred years -- when the winds are just right, or the sun is just right, or the stars are just right. Maybe all of them. I've known women who claim to see Fate in the alignment of the planets -- maybe the Wendol are like that, only coming out when certain factors are just right. Just right to feed..."
Nathaniel voice has grown almost clinical in its interest, but with the last line his eyes turn back towards the scene at the farmhouse...
"If we can discern these things, then maybe we can throw them out of balance. Drive the Wendol back to rest... Which would stop the killing right away, and give us time to set out a better plan to strike."
