Umbra frowned. These goodly people were being unusually cunning and sneaky. It was not usually their way to do something like lay a trap on a door. But then again, if it was the armoury, perhaps it was to be expected that precautions be taken. "I fear that I am unable to dispel the trap. My powers are more focused on the mind than on affecting inanimate objects. Someone else will have to do it, or else we either bypass the armoury entirely or we force the door and take our chances," he said.
