Chief Groo
The Chief Groo is a title in Utwig culture, presumably of some significance. It is not known what exactly the Chief Groo does, but the Utwig have mentioned the title before when telling of their past, specifically that of the Great Sin in which the Ultron was broken. During the Chinz-Rahl celebration, the Utwig Grand Proctor was to pass the Ultron to the Chief Groo; unfortunately, as is the belief of most Utwig, he/she did not realize the Ultron was as heavy and slippery as it was, resulting in him/her accidentally dropping the Ultron to the ground, damaging it and causing it to cease functioning; however, some Utwig theorize that the destruction of the Ultron was actually the result of a conspiracy, rather than a "serious case of butterfingery".
