this world is a lot more different then your normal one. Humans live in tribes, devided by territory and bloodlines. Those groups are ruled by one dominant and 'the mother' and their children. The dominant one can be any gender and is the leader and 'the mother' is the only human in the group with a womb. The leader and the mother does not age after they bond. The others no matter the gender all have male anatomy down there for reproduction. Only the leader is allowed to lay beside the mother and if she dies chaos errupt. The mother is treated like a goddess because she is. She is the second in rank in the hierarchy and if pregnant the first. She is the only one capable of giving birth. Average groups are formed from 15 people so they can survive. There must be at least 1 mother in each group for the survival of the bloodline. The mother not marely create life. She heal and comfort. A mother is created by birth but can officially be claimed at their 20th birthday. Here scars are prove of strength. If you do not bear at least one by 5 years you are considered weak and might get exiled or sacrificed to the mother for a stronger heir. Only the mother bear no scars. Because her body is devine. She is a goddess.
