Are the orcs of the D&D core canon cannibals, i.e. not above eating sentient humanoids?
As far as I can remember, Tolkien’s orcs seem to have no qualms about doing so (thanks for the link, Flamma), though I’m not sure they would’ve eaten their own kind as well.
What’s the official stance (if there’s any) on the feeding habits of DnD’s orcs?
I’d be most interested in v3.5’s “core setting” or that of the upcoming Next’s (and least interested in v4’s anything :)), though a comprehensive but abridged history could be a nice plus.
