A donation is the Femarctic equivalent to a human daughter. When newborn she’s called a ’doe’, an affectionate term in the Ramaxi language that is also applied to lovers, or strangers. A Donation gestates forty-days within her birther (a Zaxiri). Upon delivery she is collected by her registered maker (the caregiver licensed to take her home–almost always a Subak, typically with Bizak and or Hizak partners).
All Femarctic donations are born with a full set of small teeth that grow as they mature. They’re physically capable of holding up their head, and sitting, by the first week.
- Bizakidoe can put both hands together intentionally at birth.
- Hizakidoe are capable of facial recognition at birth.
- Subakidoe are often born smiling, but with limited vision.
- Zaxiridoe are born crying, until skin contact is made with a maker.
- Marixidoe are born screaming and kicking; they do not settle until the soles of their feet come into contact with something.
Fifty days after her birth, she begins walking, and is then considered a donat.
Subakidoe are usually the first donats to begin talking; if being raised in a pod with a Zaxiridoe, they will begin talking to each other before they can articulate proper words. Zaxiridoe also begin displaying signs of overt affection in their donat years. Hizakidoe will articulate actual sentences faster than others, because they develop comprehension sooner; this is due to the constant observation of, and intrusive communication with, their makers. Bizakidoe are often the last to communicate, but as donats they are easily contained, and capable of solitary play. Marixidoe require constant supervision and structure, they are boisterous when they learn to walk, and are often too rambunctious around weaker siblings.
A young donats brain develops functional cognitive levels on par with pre-teen humans, by age eight. At age ten, donations leave home to live and learn with their own castes, but true intellectual adolescence begins at age twelve, while away from home during this caste-specific education. They attend caste-training for up to six years (Marixi and Hizaki remain in caste-specific training eight years); these years are called ’donational years’. In these years they mature, and their social skills develop within the confines of their own castes. They’re considered adults once they reach the age of eighteen, but are not considered citizens, until their caste-training is complete.
