All three castes are very different from one another and might almost appear to be different species to the casual observer. A Worker looks, thinks and behaves so much differently than a Warrior or a Breeder that it is sometimes difficult to believe that all three could have hatched from the same cluster of eggs!
There are "swimmer" Hiver who can be quite massive and work in sub–aquatic environments; there are "nurse" Hiver who have very soft external shell plates which allow them to work with infants and other delicate objects without scratching or damaging them, etc.
Hiver are not telepathic but this is a race that really knows the meaning of the phrase "family values". Even in Humans there are some empathic bonding events in families that seem to defy an easy explanation — for example, the uncanny connection between identical twins or the way some people seem to sense when a close relative is in trouble. These phenomena also exist among Hiver since all Hiver are essentially members of a very large extended family.
To a Hiver the members of his clan are brothers — even the ones you don't personally like are still blood to you. And since a Hiver's mother is the object of almost all the feelings that a Human being would call "love" — the child's love of parent, the student's love of a teacher, the soldier's love of country and the awe that some men might feel for a beautiful, remote and eternally unobtainable woman — it would be natural that some Hiver would automatically sense if their Princess was threatened or injured, much less killed.
Needless to say, they would react very strongly...
The following are brief synopses, with links to full description pages.
Some royalty are extremely cunning, politically and strategically adept, and deeply involved with planning and command of military ventures — the Queen tends to be such a Hiver, for obvious reasons. Other Princes and Princesses can spend a whole lifetime without really touching on any kind of military service at all. There are whole clans dedicated to colonizing, mining, farming, etc.; they accumulate power, wealth and influence by providing (and thus controlling) valuable commodities and services.
The Hiver Princess is the absolute–ruler for any given clan and the female Hiver capable of reproduction. Her children are loyal to her unto death.
Princes are the male Hiver capable of reproduction. They are very influential in society, and are, without a doubt, the Hiver that express the most individuality.
Mating between Prince and Princess is a very private matter. Hiver Princes and Princesses have a mode of communication which involves their personal pheromones. At the flirtation stage of courtship these are released as an invisible aerosol — like cologne or perfume. As things become more intimate between them the Prince caresses the vulnerable wing membranes and the antenna–crown of his mate, delivering his pheromones to her bloodstream more directly; she finds this extremely arousing and pleasant and releases her own pheromones for his pleasure.
Warriors are the second most predominant type of Hiver. They are used for mainly military purposes, but are also perfect candidates for things such as arctic exploration and toxic waste disposal. If it's hazardous, it's the Warrior's job to do it.
Workers are the predominant type of Hiver and are commonly used for menial tasks such as cleaning and maintenance.
