Sessativa will also follow into the left room. It's up to Zork if he and his dogs come along.
Out of Character: Icon! The Dungeon Master said all were healed earlier, let it go
In Character: Seeing that the dogs did not find anything Zork decides to do a quick search of the immediate area to see what he finds that the dogs would not.
Search nearby rooms that the dogs have already covered. Not any that they haven't been. Even while searching his dogs are with him.
Zork takes a torch and sets them a light so no more of the awful creatures grow to harm anyone else.
Out of Character: Just checked the map, not sure where we are but will search the next room in the same way with my dogs.
