The priestess of forest gods and Lod, one of strongest paladins, conduct an important fertility ritual, enjoying each other. From the right father and the right mother, the right child must be conceived, which can play an important role in the life of the tribe.
Each tribe - and they were both purely female and purely male - had their own domestic gods, that protecting fertility. Their symbols, like the priestess's magical jewelry, increased the chances of fertilization and recorded partner information to prevent incest.
The rule of breeding rituals does not imply further meetings with children, therefore Lod may never see his child.
Forest peoples are really different from people, they are much more enduring and stronger. If they weren't conflicts with each other, humanity might not have survived.
