Orcs "ask" for their spells from the land rather than using command words.
Luna's vision walk with the Crone of Maltak sums up some of the Orc War, such as why not all orcs were conquering warriors and the "official" reason for the war.
When Melna first appeared in the comic she was called an ecomancer, which is a name I readily confess I took from The Pirates of Dark Water in a one-time nod to that great cartoon. "Noy jitat!"
Hope these links were helpful! I'm strangely "off" because my wife and I are still in the process of moving, so these linky reminders also helped get my head back into the groove of making comics.
That's all from me for now.
