Ogre Deserter

The Restless Isles
If you try to talk to him, he will reply:
 * Ogre Deserter: I do not care what Ghola-Fan says. Clan Runetusk does not need monsters from Khyber to make us mighty! When the brain-eaters tire of feasting on savages, they will turn on us. We are nothing but meat to them. But I have no proof, and my brothers will not listen....
 * You: (Diplomacy) I am hunting the brain-eaters. Will you help me invade their lair?
 * Ogre Deserter: (Failure) I will not fight for the tentacled monsters. Neither will I betray my own kind to strangers. Your help is not needed or wanted here!
 * Ogre Deserter: (Success) ?????????????
 * You (if with Ogre Khan's Skull): In Ghola-Fan's Compound, I found the skull of a mighty ogre. It was shattered by the brain-eaters....
 * Ogre Deserter: The ogre roars in triumph. 'This will prove to my brothers that we have been tricked! The Runetusks will never again be slaves and food for the brain-eaters! I will show you how to kill our enemies, but first you must give me the skull.
 * You: Give the Shattered Ogre Skull to the ogre.
 * Ogre Deserter: The brain-eaters betrayed my clan. Kill them! Kill them all!
