I've been picking through the binary of .esp files and thought I had it figured out.

You can see the different sections described in the CREA page: http://www.uesp.net/wiki/Tes4Mod:Mod_File_Format/CREA
It's like this for most records that I know of.

Even though the same UESP site doesn't mention any major difference at all: http://www.uesp.net/wiki/Tes4Mod:Mod_File_Format/NPC

Anyone know if the NPC section is just in some other encoding scheme? Or is there something else I'm missing?
