Syntax: pledge <cabal outer guardian>
pledge none
reject <player>

Pledging to a cabal makes your intentions clear that you wish to join a
specific groups cause. You must be at least level 15 to make a pledge to a
Cabal. The Cabal Leaders will hear when you arrive and when you leave the
Realm, and you will hear when the Cabals outer guardian comes under attack.
You are only allowed to pledge to a single cabal, so make your choice wisely.
You cannot pledge to the Battle cabal and must speak with Tahren to become a
Village Applicant. You cannot pledge to the Empire cabal and must speak with
the Imperial Recruiter or a member to take the Blood Oath.

If you wish to renounce a pledge you've made you can 'pledge none'. You will
however not be allowed to make another pledge. This will not bar you from
joining another cabal, but will force you to speak to the Leaders about your
past and why you changed your mind about your path in life.

Cabal Leaders will be able to do 'who applicant' and see who is currently
online and has pledged to their Cabal. If a Cabal Leader deems an applicant
unfit, they are able to 'reject <player>'. This is the equivalent to the
applicant doing 'pledge none'.

The Cabalwars command will show the number of true members of the Cabal, along
with the number of applicants to the Cabal.
