Dreskay is an extended family. The Droyne extended family is a grouping of several (between three and 18) tyaflemin. The association of many Tyafelmin provides a larger gene pool and allows the offspring from the component tyafelmin to come together and form new tyafelmin.
Occasionally, dreskayin esivoy (schism). They split and become two or more dreskayin, dividing the acquired assets between them and then going their own ways. Such splits may be due to local economic pressures, famine or drought, or growth of the family to excessive size. Split families may or may not maintain connections and communications with each other.
As families grow in size, they may send out iyuksimin (tendrils), small groups to explore, investigate, engage in trade, or just travel. Such small groups (usually balanced to include one member of each caste) give the young experience, provide and opportunity for profit or earnings, and sometime relieve the family of the requirement to support the wanderers.
The dreskay is a family, but it is also part school and part grouping of friends; it probably most closely represents the original social unit of pre-civilized Droyne on their lost homeworld.
