All Earth's Children characters belong to Jean Auel. All Harry Potter Characters belong to JK Rowling. I just wrote this for fun, not profit.
the climax and the denoument
The climb up the hill was to be Latie's last clear memory of her time at Hogwarts. Dumbledore had been sympathetic, but insistent that she leave. It took several days research through some of the oldest archived parchments, and his plan was not without risk, but he was able to send her back to her people with a high degree of precision--she had not been missed.
Dumbledore had gently obliviated her memory so that she would remember the time in Hagrid's hut only in recurring dreams, and her brief stay at the castle was no more than disjointed images.
Latie woke up after her "dream" and lay in her bed, going over each detail. She had come to respect the root. It must carry powerful magic to cause such vivid dreams, and she was a little afraid of it. Furthermore, it seemed to her as the days went by, that sometimes Old Mamut would look at her strangely. She had no calling to the mamutii, however, and Mamut passed into the spirit world two years later without her ever telling him of the dream or the root that caused it.
For the most part, she went on to live a normal life, although a long one. She had her recurrent "dream" at times of great change in her life--her matrimonial, the births of her children, the deaths of Nezzie and Talut, the arrival of the grandchildren, and the death of her beloved mate.
When she finally held her great-grandchild for the first time, she felt a stirring, as if the veil between the dream world and the real world had blown aside, and all she had experienced at Hogwarts Camp came back to her in real, vivid relief. For a while she sat, cross legged on the mat beside her sleeping granddaughter, holding the next generation in her arms, as memories washed over her. Two strange shelters, exotic animals, outlandish clothing, a man bigger than Talut, a man older than Old Mamut and another man with the blackest eyes she had ever seen. And the Jondalar-boy.
She came back to herself when her own daughter reached over to touch her on the shoulder. Latie laughed a little, and handed the baby to its grandmother. Four generations around the same hearth. She could be forgiven a touch of senility.
Latie herself died before the baby was three summers old. She was not to know that the little girl, to whom she gave the name Rodie, was to grow up to be a powerful Mamut, and as the millenia rolled by, from her line would decend a line of powerful wizards. Among these wizards was Albus Dumbledore.
