A chronicler of events who tries to curry favour with all the subjects (people) he writes about.
1. How can you take his history books seriously? He's no chronicler - just a cronycler of the high-ups, he'll crony up to any such.
2. So you didn't like what I wrote about him, eh? Well, you'll just have to lump it, won't you, I'm not the chronicler you were looking for.
