So it has been a long time, but I thought I remembered more commands to be used within a cabal in certain rooms like near the trainer. I can not for the life of me remember. 
EDIT: I guess my working is wrong as I don't mean help cabal commands
Cabal Commands
heal train and list are all that I know of.
True story ^^
Ok, maybe I didn't have enough RANK at the time to use the commands.
service is the command your looking for.
Service in the room will show you what is available.
