Olan'vora is a Varro biochemical reaction. During and after mating, the epidermal skin luminesces. Psychological bonding increases with exposure, stimulating the areas of the brain responsible for love. If allowed to advance, the olan'vora becomes permanent and the couple becomes bio-chemically linked. Separation thereafter is rare, however, up until this point the effects will diminish in a matter of months with decreased exposure. Withdrawal symptoms can be unpleasant.
