Anyone Know the Names of the Writers in the Shadow Series?

[wizcreations]

I know Peter and Val are Locke and Demosthenes, and in the shadow series after Peter is Hegemon, two new writers emerge, one is Petra, I believe as Lincoln, and the other is???

What is the other pen name used (Lincoln and who)? And is it Peter who writes it?

Peter writes Lincoln, who is basically the re-birth of Locke. Petra writes the Martel essays, who is essentially Demosthenes.
