Sentinel Paxin  

I was exploring Icewell one day, and decided to talk to this guy and see what I could find. This is what I got
[Sun May 13 17:47:41 2001] You say, 'Hail Sentinel Paxin'
[Sun May 13 17:47:41 2001] Sentinel Paxin says 'Greetings offlander. I see you are exploring our beloved Keep. By order of the Dain all offlanders that have been friendly to our people are permitted to explore all parts of Icewell Keep save this door I guard. Enjoy your stay.
[Sun May 13 17:47:46 2001] You say, 'What door'
[Sun May 13 17:47:46 2001] Sentinel Paxin says 'Why this door behind me which I stand in front of course. You didn't by chance fall on the ice and hit your head I hope good Erudite. By order of the Dain, none are permitted to see or go beyond this entrance.
[Sun May 13 17:47:47 2001] Chamberlain Krystorf begins to cast a spell.
[Sun May 13 17:47:50 2001] You say, 'what is beyond this entrance'
[Sun May 13 17:47:51 2001] Chamberlain Krystorf begins to cast a spell.
[Sun May 13 17:47:51 2001] Sentinel Paxin says 'Why beyond this door lies the most wonderous. . . oh wait, I can't tell you that Erudite. All I can tell you is that the door has also been magically sealed by our Grand Historian. Please move along now and enjoy the rest of the Keep.
I couldn't get any further.

There is a door behind him that is magically locked. Anyone know where it goes to?
