I guess this is off topic "GT" command. What's the use of this?

I haven't tried it, but I don't think these commands work in any of the sources here.
Try building a quest server to check them out, I remember, back then, I deleted them in my source.

They are commands for quest, like cleaning the sector, creating npcs, etc.The use of them is only active in debug mode, if you want, just remove the debug tag of the command and the packet
