Korrak the Everliving

There's something not quite right about all of this... Did anybody think to burn Korrak's corpse? Those trolls will stop at nothing to revive their fallen leader - as blue skinned pagan man-beasts often do. Just keep your eyes out, <name>. Don't be alarmed if Korrak makes a surprise appearance; and if he does, I want him executed - his corpse burned to ashes. For good measure, lop off his head and bring me his skull before you ignite the lifeless mass.
