NPC responding to hail, but no quest file?

[Traul]

I've encountered a strange problem with the NPC Ratraz in neriakc. I don't have any quest file for him in my EQEmu/quests/neriakc folder, yet he will still respond to a hail with a message. If I create a file Ratraz.pl with some new message for hailing him, it will work but I will also get back the original message when there is no file.

There's no npcid.pl file in the folder for him either, and I don't seem to see anything in quests/global either. I've tried using the explorer search function on the entire quests folder but nothing came up. Any ideas what's going on here?
