Maestro Nikola:
I want to find out how the Core works. I should be able to do this with some help from you...
Among the creatures inside the Cruma Tower is one called Porta who is thought to be a golem. Magic and spirits... We Dwarves don't know much about such things, but when it comes to 'artificials' like golems we know them better than anybody else. I think we shall find something if we inspect inside of Porta... To do this we need a sample of the heartstone.
Please go into the tower and bring us 10 Heartstones of Porta.
