Antagonists is stil in stock in our warehouse. I'm not sure why there would be any shortage of it in distribution unless whoever you're usually ordering it from hasn't re-upped their stock in the last few months.
Guardians of the Forest is out of print, for sure.
I'm certain it's not normal the magus Galafre (p92) has twice the spell "posing the silent question", but is there any idea on what spell he should have in replacement of the second?
