I am creating this planet which is mainly barren and desert around the equator, but towards the poles there are huge mountains with glaciers and frosts. There is not much sea around. The inhabitants are humanoids with very strong animal characteristics, in a society that the jungle law applies (survival of the strongest, tribes, etc.). So, I consider having two moons, one smaller and one quite large, mainly to be used as a metaphor, showcasing the society's inequalities, their sudden and violent mood swings and their unpredictable nature, thinking also that two moons could affect their behaviors in such ways.
So, my first question is if my thinking makes sense from a scientific point of view? The existence of two moons can be aligned with my planet's geography, i.e. a mainly desert planet, with few oceans - that are considered as extremely dangerous and some very few but very big frozen mountain near the poles? Two moons could affect behaviors, right?
My second question is if it is possible (scientifically again), the two moons to share the same ring - in an "infinity/mobius strip" shape maybe? I would really like to use it as another metaphor for the inter-connectiveness of good and evil that exist in everyone and to add a cool effect maybe. :)
