With the guards busy, Raz took optimal opportunity to initiate his plan, and with that, he gracefully floated down with no noise at all, and looked at the slaves around him, signaling them to be quiet, and as 2 guards turned around, he shot two yellow beams of direct light at them, and they passed out.
Raz watched them fall, and looked around, and spoke in a soft manner, quiet enough for those outside to not be able to hear a peep, "Everyone, listen... there's a corner of this place that touches the outer wall of this city... I can provide refuge at my home if you trust me and follow me... if not, then stay here... stay here and be auctioned off for food or other displeasurable deeds..." and with that, Raz hopped up onto the rafters and soon dropped down by a corner and as he placed his hands on the stone wall, it started to swirl and morph as though it had returned to clay, until it became a clear hole, "Run! Run now! I can only hold this for so long...", waves and waves of slaves started to rush out of the building to the outer area of the walls and right into a brush.
Struggling could be seen clearly on Raz's face as he continued to hold this doorway open for thousands of slaves, and he soon looked back at Carl, with beads of sweat falling down his face, "What are you doing! Run already!!", and at that, the doors opened at the entrance of the barn and guards yelled things at Raz, but before they could run in, he shot a fireball at the roof of the warehouse over by the entrance, collapsing on those guards and slowing them down for quite a while.
The exit was slowly starting to close, and aside from a few elderly, Carl was the only one left, "RUN!"
Raz had become much more tired from the fireball, but was struggling immensely to keep the hole open.
If any were familiar with the Castle's Grand Wizards, then they'd notice that Raz is, or rather, was one before the war.
