Bring the Frozen Eggs to Betina Bigglezink.
The eggs you brought were to be used in Scourge experiments to create a plagued dragonflight. These frozen black dragon eggs would have been invaluable in their studies, and would have assuredly quickened their timetable.
Now, it is time we ended their research.
Take the frozen eggs to Betina Bigglezink outside. She is well-learned in science and alchemy, and has produced a weapon we can use against the Scourge. With your help, we will deal them a heavy blow.
