Underdark Slave PCs

[onivel]

I need some clarification on the rules for Underdark Slave PCs... 

Can they or can they not be allowed to be freed. 

I was straight out told point blank by staff that Honey and Ember could not buy their freedom and be freed. We either had to have them enslaved by new owners or they needed to be retired. 

Now I am hearing that a slave is allowed to be freed. 


So am I hearing incorrectly?... did the rules change?... or were me and Sphene forced to retire two beloved PCs for nothing?! I need answers on this.
