Who messes with kobolds? - Oldbook adventure

It's been almost a year since I left my D&D hero Oldbook standing in front of the kobold cave. 
Finally I found time to move on with the adventure.

One would expect at least some guard in front of the kobold cave, but there was no one.
First cave had two doors at the bottom. One was locked, so Oldbook decided to go for the other one. It led to the kobold armory, that also served as a stable for riding giant lizard. As the beast was chained to the wall, Oldbook easily avoided it.

There was nothing among the kobold armor and weapons that our hero cold possibly want, so he moved on.

Next room was some kind of office. Lone man was working by the table. Noticing Oldbook, accountant run out of the room in panic.

Oldbook decided not to go after him. He check the desk and found lots of documents with proofs that innkeeper was cooperating with kobolds. Bard took the documents and returned to village, presenting them to the chieftain.
Innkeeper was immediately arrested. He was surprised with the situation. It seems that accountant never bothered to inform his boss about unwanted guest in the office.

Next thing Oldbook did was to return to the office within the kobold caves. Accountant was still there, working as if nothing happened. Bard called on him and persuaded the man that he can be a better employer than the innkeeper.

Later that day, accountant organized a meeting between Oldbook and old kobold shaman.
Yes, kobolds could explain everything about the grave below the Deepcold, but not for free. There was the question of the illness that was weakening the tribe. Tribe can only by cured by a meteor stone owned by the witch living in the caves deeper in the mountains (Rory Story Cubes - falling star + cauldron). If Oldbook manages to bring the stone to the shaman, he will tell his story...
