The second gate opens, another dwarf enters. This one wears a full plate armor and the strange looking shield too, but instead of an axe he have a flail. "I have no idea what is the name of this dwarf, but he looks angry..."
The third gate open. Another dwarf enter from there, he wears a chain shirt and have a loaded repeating crossbow, with a strange looking shield as well. "This dwarf name is Grubb. And no, I have no idea how he is going to shoot his crossbow with that shield on him. I hope for him that he can aim well".
The fourth gate opens. A halfling goes out of there. He wears a studded leather armor and wield a rapier on the hand that don't have the shield on it. "Finally, someone who is not a dwarf! isn't that refreshing?"
Finally, the fifth gate and the sixth gate open. "To spice things up, we brought some goblins and kobolds prisoners who will fight everyone. Don't worry, they don't have a shield that makes cool things."
There are 5 kobolds and 5 goblins.
I probably misses something and left a lot of things complicated, so please ask.
