Magister Gauen:
I am Magister Gauen. Ah, yes, Commander Kadesh and the Crescent Bow... That is a story that I'll never forget. Commander Kadesh is the most daring among all the sons of Shilen. He eats like a horse, yet he is always hungry! He is constantly growing... This caused anxiety among the Gods, and they gave instructions to the Elves on how to kill him with the Crescent Bow. This bow was kept in the Ivory Tower for a long time, and 20 years ago became useless...
...but if what you are saying is true, we need the bow...
I can restore the bow, but it will not be easy. Most of the materials I will need you can find in the Ivory Tower, but some you'll have to find elsewhere... A horn from a manashen gargoyle, a Reinforced Bowstring made of the swamp spider's web, a Mithril Ring which can be obtained from a road scavenger and a chitin of a swamp stakato which can be obtained from a Marsh Stakato worker, a Marsh Stakato soldier, or a Marsh Stakato drone.
