You want stories that are basically torment/tortur fics in the Grab-bag threads?Eep. (Unless people to decide to make it Au's and give them all happy endings)
Those could make for cool Grab-bag fodder.
I had enough problems with image Embala made for 'Still'. No offence meant. ^^ Sorry.
On the whole 'too old to Recognize' issues:
It makes sense to me the Wolfriders would at some point become unable to reproduce when and if they reach an high age.
In my mind, Purebloods likely can Recognize whenever it hits them.
Wolfriders just stop at certain age due to their biology. (just my opinion.)
I saw somebody mention Selnac and the issues she had with Recognition.
Years back there was an thread that theorized Recognition had some problems in the beginning, such as misfiring.
The ideas on that thread made great sense to me and I've always thought it was just Recognition being an absolute asshat/misfiring. I mean, Selnac was an healer. She knew wasn't going to have any more children. (Book says so itself.)
