according to loadstone there are at least 7 link shells on sargatanas which might fill that role the largest being odins elites with 9 members, you would have to talk to the linkshells master or "officers" to find out if the channel actully fills that role.

for those who don't know there is a search function in the loadstone website which allows you to see what linkshells exist on a particular server and who the master, officers, and members are for that linkshell.

this feature is located under "community -> linkshell" on the main menu bar
