Indruck Niule, born in a gripplis tribe and interested in explosives early on. The little Grippli's attitude wasn't exactly appreciated, before he was even able to talk he got his hands on some dynamite in the mines, by way of sneaking of course. This stick of dynamite didn't exactly do him well though, collapsing a tunnel in on him and damaging him permanently the grippli gained a slight twitch along his left upper arm that extends up past his neck. His left eye constantly twitching.
It did not take many years before his tribe got sick of his mischief. One event in particular nearly wiping out the eastern quarter of the settlement. The others acted after that, pushing him away from homes, knocking him out and leaving him in the wilderness. Waking, he sought out his home once more, only to find a human settlement, seeking shelter and food was what he wanted but the guards did not see that. He was seen as a pest and run out of town. Indruck resorted to sneaking once more, finding what he needed and escaping with the aid of his own little experiments.
He made his life like this, sneaking about, he only saw guards as obstacles, and the innocents he was taking from simply needed to move out of the way or be hurt. It wasn't all bad though.. He made friends here and there, traveling with multiple little gangs from time to time. One in particular, Malvin Gaise, a gnome of tricks, those two were quite the crew. Indruck slowly adapted more and more to his lifestyle, instead of wading in the swamps like a normal Grippli, he was leaping from building to building using the natural webbings on his body to Glide himself to relative safety.
Malvin introduced Indruck into the religious world of the Goddess Calistria. Teaching him that he was always under watch. From that point forth if Indruck would make stops at Temple's regardless of who it was for. These buildings brought a sense of safety to him, refusing to believe that anything bad could happen in a proper temple.
The two trouble makers eventually found themselves in a the cliff-side metropolis known as Urbis Turrim. Currently residing there doing what they please, Indruck taking up his experiments in either the sewage tunnels, or abandoned mines that litter the cliffside.
