I am going to go post this over in the Belenos thread as well, because i am pretty excited about it.
I e-mailed Loic and asked about the availability of Errances Oniriques, Spicilege, L'Ancien Temps and Chants De Bataille. He got back to me saying that I was very lucky and that there was only one copy of Errances Oniriques left and to get back to him as soon as possible if I was going to make the order. So my latest purchases are:
Belenos-Errances Oniriques
Belenos-Spicilege
Belenos-L'Ancien Temps
Belenos-Chants De Bataille
He gave me everything plus the shipping from France to the U.S. for $72.
Expensive, but worth it imo, considering how hard it is to get a hold of these.
