Wait for Insom'ni to attune the Enchanted Brass Key, once the key is attuned, return it to Hydromancer Flakereef in Caelan's Rest.
Now, I will do what I can to restore the attunement to this key. It shouldn't be that difficult, the magi who left the magic did a poor job with leaving magical traces upon it. Step back, I will do as you asked, it shouldn't take long. When I am done, you may return to the one who sent you.
How have you fared? Have you gotten any answers about the key?
Now that the key is attuned, and enchanted, we can begin our planning to destroy Hydromancer Lapidis.
