There's been a number of times I've wanted to bring someone that wasn't in the cabal into the cabal for various reasons. I do like this idea. There would have to be a timer on it else it could be abused by allowing people hide in other cabals. We can't have that.
And by immediately you mean on the next tick. Give them a chance to get back to their escort.
Ah, 'escort' may be a better command name.
Syntax: Escort
Though perhaps we can do both, Escort and Permit. One requires the victim to be in the same room as the escort else they're booted, the other allows them more reign to wander. The latter could be limited to allied cabals and members of the feeder clan in good standing (V/T).
... No, thinking about it, being thrown out on the next tick is no good (based on the fear of guards) unless they're unable to move like when you hit level 6 in the mud school.
Possibilities:
Have it auto-expire upon leaving the cabal grounds and hostilities.
Length of timer depends on relation of the cabal in question and/or is a member of the feeder clan and/or is dependent on the level of the victim. Level 30's < Level 50's < Neutral cabal < Trade Cabal < Feeder Clan < etc.
Will not work on with vendetta'ed cabals.
Cooldown timer.
Can't use while either party is bloody (not that you'll get past the guard).
