Description
After you foiled a plan to destroy the Grand Tree things have been quiet in the gnome world. Brimstail has found a strange machine, though, built by Oaknock the Engineer during the Gnomes' Golden Age. What does the weird device do? Why on RuneScape was it built? If you agree to help this bookworm gnome get this confusing device working, you will learn a little about gnome magicks, gnome history, and you will start to uncover a new threat (or is it an old one?) to gnome security - a threat that is a lot harder to see ...
A small crystal seed — Either take it to Ilfeen in Tirannwn or use it on the singing bowl by Brimstail to get an enchanted crystal saw. Then, talk to Hazelmere. It allows items (that require a saw) to be made three levels above your Construction. It has a limited number of charges (28), but the recharge is free - use the bowl again.
