I have never had to rebuild before. The ocean has always provided what we needed. We have had to move before, when the waters became too polluted or hunting became too scarce. We had to get used to new hunting grounds and new lands to walk and mate. It is important that the place where you will be living meet your survival needs.
We are never raised by the men who father us, and I understand that Arva has a great desire to be merrow mother, if this places you at ease.
