On the Knowledge checks for identifying monsters, I will often stack spoiler blocks within each other since you gain more information for each 5 full points by which you exceed the DC. In this case, you do not need to roll a second Knowledge check. If your original check beat the next result, you may read the next spoiler. Remember, this is the honor system. Please do not abuse it.[/sblock][sblock=Knowledge (dungeoneering) DC 12 to identify the creature]This creature is a skulk, a member of a race of subterranean humanoids with superb camouflage that allows them to blend in with their surroundings.[sblock=Knowledge (dungeoneering DC 17 to know more]A skulk's stealthy abilities extend to evading magical means of detection as well as tracking. It is extremely difficult, if not impossible, to track down a skulk who has fled.[sblock=Knowledge (dungeoneering DC 22 to know more]Although not physically powerful, skulks are cunning and often travel in groups, using their stealth to take opponents by surprise. They often serve as minions to more powerful creatures in the Underdark.[/sblock][/sblock][/sblock][sblock=Knowledge (history) or bardic knowledge DC 25 to recall information about Jzadirune]Jzadirune is a gnomish enclave below Cauldron that was abandoned 75 years ago after it was struck by a magical malady known as the Vanishing.

"I'm afraid I don't know exactly how many of them there are," the gnome explains petulantly, "but they usually come in pairs or threes and often leave the shop wearing cloaks. There are actually two kinds of creatures. Tall ones and short ones. This is a tall one. The short ones are sinister gnomelike creatures (I assure you there is no relation) with pallid skin, large noses, and soft black hooves for feet. They wear black cloaks and cowls that help them hide in shadows.
"They could come at any time, so time is of the essence. They usually come at night however. I suppose it is all the better for them to carry out the kidnappings in the dark."
