4) The Metallograph talks about experiments the Giants have undertaken on a Cruma tortoise. Cruma were, like the Giants themselves, Genesis Creatures with a very long life expectancy. Lorain is fascinated by the prospect that a Cruma may still exist and sends you to Priest Shegfield in Dion for more information.
5) The Elven Priest is in the Einhasad Temple on the hill north of the town.
6) Shegfield tells you that the Cruma are now extinct. The last of its kind fought alongside the Elves in their war against the Humans and died a heroic death in the place now known as the Sea of Spores while covering the retreat of the Elves.
8) You will probably remember that Kusto is in the Blacksmith workshop at the west gate of the town.
9) Kusto considers a purely historical research on Cruma tortoises unprofitable. Nevertheless he gives you 121,527 adena for your trouble. If your character is between level 42 and 47 you will in addition get 309,467 exp and 20,614 SP.
