 * Merlin using his alter-ego "Ahbraim" to be present for Alahnah's birth.
 * Also, one of Alahnah's names - Naimu - is very probably the modern Safeholdian pronunciation of "Nimue."
 * almost certainly, as Cayleb had indicated his desire to name his first child after Merlin/Nimue after Merlin saved Sharleyan from being killed or kidnapped in By Heresies Distressed. That conversation was a Heartwarming Moment in itself as a matter of fact.
