Backstory till campaign start

Scribbles was born in a small colony of kobolds living in the sewers beneath wildruun. after a few years of resonably peaceful living a group of adventurers found the borrows below the sewers and soon everyone, including Scribbles, was scrabeling to get away. Having no clue where the others went he decided to hide out in the alleys behind the market ward. After a few days of scavenging for food he ran into a young sage named Petran working in the cobalt reserve.
Taking a liking to Scribbles, he brought him inside so Scribbles could serve as his assistant and friend. All went well for a while, Scribbles starting to show promise in the arcane and Petran was getting close to finishing his research about why gnomes are assholes (atleast thats what he told Scribbles), when some found out there was a kobold running around in the reserve. Running to grab his favorite book, Volo's guide to monsters, he was caught right when he got to it. Trying to hold on to it, it got pryed out of his hands. A few moment before he was gonna get drop-kicked in to the lower atmosfere Petran showed up to save him from the guard. Giving him a page of the book and dimention dooring to who knows where. Scribbles ran into the wild before even looking at the page. When he did, it turned out to be the index of Volo's. Vowing to complete the book once again and show how far he'd come to Petran he glued it to the first page of his spellbook and wandered off.
