Ba'al's lo'taur had been in the service of the System Lord Ba'al for 24 years by 2002, possibly his entire life. During that time, he had seen and heard much. So much, in fact, that he had concluded that the Goa'uld were not gods. However, he continued to serve them anyway, for he himself hoped to be taken as a host, in the chances of one day ascending to the rank of System Lord. Dr. Daniel Jackson, posing as Yu's lo'taur Jarren, unwisely imparted his views on the Goa'uld to the lo'taur. As a result, Ba'al's lo'taur warned Yu that Yu's lo'taur was untrustworthy.
