patch 3.51

[Culfinrandir]

Auriana in mor dhona sells them for poetics (Allagan Tomestones of poetics - Other, 6th from the top), but you can also buy them in Idylshire for lore, or as mentioned above with GC seals. You do not have to be on that step of the quest, can purchase them anytime prior.

Thanks, I'm definitely going to check again because they weren't there yesterday. If they're still not there I'll report it as a bug. Had to waste Poetics on crap yesterday as I was capped & won 500 on Khloe. >_<
