As for the WHY:
Choosing professions for two parents in Khan character generation is confusing to me.
Suggestion:
- Krans have no way of knowing their parent since they transform to their adult form at some early stage of their cycle (Metamorphosis while being left in a cave?) so they can’t pick any.
- Krans look after their young until they are capable of sustaining themselves because they see them as a renewed/prolonged self-existence. They may choose only one.
- Krans have a unique way of reproducing which involves passing limited number of memories to the next generation on a cellular level. (suggesting 1-n, but let’s stick to 2)
- Krans do pair up to provide a healthy social emotional environment for their young. (Suggests that a Kran may find mate from other races)
- Krans do pair up, to support the physiological development of their young. Parents provide them with body fluids (blood and acids) on a regular basis, and having 2 individuals donating is easier or makes one more resilient.
- Or any combination of the ones above
As for the seriousness:
I think this is a minor thing that should take the last place in a prioritized sense.
