Comparing PEQ to AX Classic database

[EQstarr]

I've been building my own database with a combination of data from PEQ and AX Classic. I was working with Everfrost the other night, and I noticed that there is a difference between NPC Types, Spawn 2, Spawn Groups, Loot tables, and Grids.

I know PEQ gets all of their information from Live. Where does AX get all of their information from? Does AX have Everfrost (or any other zone) how it used to be originally, or did they just program the zone in their own way? I didn't think Everfrost was radically changed on Live, but there is definitely a difference between the PEQ version and the AX version.
