We would have four people, since I'd send Trapezoid's rogue being Ifrit. As in for information on the Klug, not much has been fleshed out. They are one of the five tribes in the Compendium listed under the NPC organization 'Forest Tribes'.

To summarize, they're a relatively primitive group of two or three thousand, known for being particularly warlike. I didn't go into specifics, but they are led by a caste of magic users. The Klug have always been quarrelsome, and several tribesmen tried to loot the Mutig village after it was sacked by crusaders. For those reasons, Shaige and the Mutig are trying to sack the Klug village.
