A Portable Power Source

Next we shall need to find a stable and portable source of energy to keep the ectoplasm active. I've heard rumors of a mighty elemental called Magma Lord Bokk, whose heart is a powerful magma core - an endless supply of heat!$B$BIt's said he can be found in the Burning Steppes, south of Blackrock Mountain. Bring the magma core to me and we shall have enough juice to power the extra-dimensional ghost revealer!
