The Masters' Profiles

Fallen London

So, I got bored and found these:
http://fallenlondon.storynexus.com/profile/Mr~Eaten
http://fallenlondon.storynexus.com/profile/Mr~Iron

I tried some other Masters, but these are the only ones that seem to have profiles.
Why these two, do you suppose?
And what other profiles like these are there?

Mr Iron participates in the Knife and Candle League, and Mr Eaten was used at least once to distribute an invite.
