(Especially as ninety percent of the stuff therein is classified up to the eyeballs and protected by wards that will make steam boil out of your ears if you try to read it without the right security clearance.) But I'm older and more cynical these days, and I understand the logic behind it.

The deadliest threat to any covert organization is the loss of institutional knowledge that comes with the death or retirement of key personnel. The long-term survival prospects for those of us who practice the profession of applied computational demonology are not good. Let me put it another way: I've got a really generous pension waiting for me, if I live long enough to claim it. As we drift helplessly into the grim meathook future of CASE NIGHTMARE GREEN, the final crisis when 'the stars come right,' the walls between the worlds dissolve, and the monsters come out to play, we're going to need more sorcerers than can be trained by conventional methods; we're going to have to drop a lot of our existing security practices, allow the stovepipes between departments to melt, lower the firewalls, and get these sorcerers up to speed and mixing new metaphors as fast as possible. These memoirs are therefore intended to feed into an institutional knowledge base that, by and by, will help my successors (including new operations management personnel) to survive by allowing them to avoid my non-fatal blunders – blunders I only lived through because I made them in a kinder, more forgiving age.

(Also, there is this: writing down nightmares is a really good way to exorcise your demons.)

However, as I record this account of the events surrounding the Apocalypse Codex, I'm going to have to take some liberties. For starters, even if I'm dead when you read this, other people affected by the events in this document may still be alive – and what you learn from it may hurt them.

So I'm going to have to redact some sections. Also, I'm in line management these days, and although I debriefed all the surviving participants and read all the reports, I didn't personally witness all the action.
