->''"As the vampire Kain, the only way in which you are capable of interacting with ''Blood Omen''[='s=] human cast by is killing them. This changes when you acquire the Disguise ability, which transforms Kain's sprite into that of [[InTheHood a hooded peasant]] and allows you to solicit voiced audio clips from neutral [=NPCs=]. This is only interesting for about ten minutes; you soon discover that the human race [[WelcomeToCorneria hasn't a single god damned thing worth saying]]. All Nosgoth's menfolk talk like oafish cockneys -- "good day to ya!" -- and the entire female population consists of drunken prostitutes. The vampire Vorador pointedly refers to Nosgoth's human population as 'the cattle;' the opening to ''Soul Reaver'' alludes to Kain's contempt for humanity. After chatting with ''Blood Omen''[='s=] townsfolk for any length of time, it is [[FridgeBrilliance not difficult to see from where such sentiments might have arisen.]]"''

->''"Peter Popoff ''[is]'' a notorious, alleged [[CorruptChurch faith healer and televangelist prophet]]. He was famously exposed in 1987 by James Randi who uncovered that he was being informed of believers’ illnesses through a radio receiver in his ear broadcast to him by his staff, based on conversations they had before the service (Popoff had of course led people to believe he was getting messages about their illnesses [[PhonyPsychic directly from God]]). The scandal did drive him into bankruptcy back then, but didn’t stop him from returning to the airwaves more recently to to fleece a new flock who may not be aware of the scandal.\\\
His current scheme is the typical Prosperity Gospel or “pyramid scheme for Jesus” approach: By giving Popoff money you will make God give you ten times as much money back. He is usually seen on late night infomercials where you can call in and order his special package that includes magic salt and water that you sprinkle over your check, a prayer cloth, and anointing oil. He has reportedly made over $23 million dollars on this scheme.\\\
His newsletters to his fans read mostly as a mixture of spam and cheap conspiracy theories and ''“I’m going to tell you something, but you must promise to keep it quiet. You have to understand that the ‘elite’; would not be at all happy with me if they knew what I was about to tell you. That’s why we have to tread carefully. You see, while most people are paying attention to the stock market, the banks, brokerages and big institutions have their money somewhere else... what I call the [[GrowsOnTrees hidden money mountain]]... All you have to know is the insider’s code (which I’ll tell you) and you could make an extra $6,000 every single month.”\\\
'''Diagnosis:''' ''A living, breathing monument to human naivety and lack of critical thinking skills. Few items around today augur a bleaker future for humanity than the continued media presence of Peter Popoff.''
