The Dread Empire series by Glen Cook really reminds me of Bakker. It's a very dark world with empires and sorcerers aplenty. It really has the tone of the prince of nothing series with religious fanatics and a Muhamad analogue vs and Asian themed despotism with magic nobility although that really does sell the series short at one point one of the main characters settles down to try and govern a small kingdom and the interaction of all the ethnic groups and classes that are shown puts most contemporary fantasy to shame.The one thing it lacks is the deep philosohy of The Second Apocalypse despite that it's tone is much closer to Bakker than George RR Martin, and I believe someone, maybe Pat? asked Bakker if he was influenced by it because of the similarities. Anyway if you are craving a Bakker fix the Dread Empire series should hold you over for a bit.
