Character Role Analysis
Glimfeather
Glimfeather bows out of his potential role as guide/mentor, but he does a fairly bang-up job on the information front. He's able to provide our protagonists with background on Caspian's current voyage, hook them up with Trumpkin (then warn them away from Trumpkin), and then whisk them off to a parliament of owls, who offer full, tragic backstory for Prince Rilian and the weird woman in green. Glimfeather and the owls also match Jill and Eustace with Puddleglum, which is the best piece of owl-wisdom they ever provide.
