The physical makeup is that they appear in most senses to be that of an average human, most don't age in appearance past the age of 30, however a Kerrsal have a very long lifespan sometimes lasting a few hundred years. They have the ability to float/levitate as well as the ability to ghost solid objects such as doors and walls and turn themselves invisible. The Kerrsal have the power to create and control water as well as some minimal powers over energy. The strongest power a Kerrsal has though is their power to heal, the energy for which comes from the gem firmly imbedded in their forehead of which if it were to ever be destroyed the Kerrsal in question would be killed instantly. A trained Kerrsal an also look into another's eyes and tell exactly what race they come from. A Kerrsal can also go for several days before eating if they do not expend energy using their powers. When a Kerrsal's powers begin to manifest the Kerrsal loses the ability to dream.

In the history of the Kerrsal many of them became Liches, when this happened the wisened ones of the race placed the children of those who chose the way of the Lich with human families no human family had more then one Kerrsal infant or child placed with them. Many of these children have returned to the home of the Kerrsal, those who did not were presumed dead. Their old civilization a ruin is guarded by a guardian who does not show itself unless the person is a member of the Kerrsal Wisen council or to defend the ruins if the visitor to the ruins seeks to do further damage to it.

The Kerrsal's race has been slowly becoming nearly non existent for two reasons, first is that when two Kerrsal unite in marriage it is for life and cannot be separated. And second when a Kerrsal woman becomes impregnated and gives birth, it can take months to years before they become fertile again, in essence the Kerrsal are unable to reproduce fast enough for their population to grow.

Kerrsal's weaknesses mainly have to do with their gem and their energy. If a Kerrsal's gem is destroyed they are dead, no hopes of ever fixing it. Running out of energy mostly comes from using ones energy non stop, example healing a very bad injury may cause them to pass out. Also staying awake and not sleeping or eating will draw on a Kerrsal's energy as well, rendering them unable to use most of their powers until they have regained their energy. However they are not invulnerable to physical damage either, they can take damage just like their human counterparts though their body may heal that damage quickly, but rapid damage to their body would take more and more energy to heal, the less energy they have the more chance they have in passing out, during which it takes longer to heal, as well as the less powers they have to use.
