Hestrea, the “nation” to the south of Cascadon is mostly a frozen wasteland. About 300-400 years ago it was a unified culture, with the oligarchical government housed in the Isen. However, a heatwave caused the ice upon which the Isen was built to break, and the palace sunk into the hidden sea beneath.
Since then the people have been separated into tribes, constantly at war with themselves and the environment.
In Hestrean culture there are 4 clans, Fire, Water, Earth, and Air. Clans and tribes are different. In one tribe there can be one or all clans represented. One is not always restricted to the clans they are born into. For example, if there is a tribe of Earth Clan and a child wants to be a part of the Fire Clan, they can leave and join a tribe with Fire Clan.
Those of the Fire Clan tend to have a fierceness to them. They are quick to act and tend to be fickle in, well, all things. They are powerful warriors and seek glory and honor. Due to thier combative nature, they are the most likely to be in single clan tribes, favoring the company of like-minded Hestreans.
When a prt of a multi-clan tribe, the Fire Clan members are usually scouts and hunters. They mark thier skin with tattoos to commemorate great kills.
The Water Clan are the most likely to settle. Of all the clans they desire most to cultivate and create a steady civilization. They tend to migrate in the northern, more habitable parts of the country, particularly near the Frozen Swamp.
Water Clan members are useful as healers, and have had some success in unlocking the secrets of magic. They tend to surround themselves with other clans for protection and utility, but the Water Clan members are usually in a position of power.
Of all Hestreans, none are more curious than the Earth Clan. Once an Earth Clansman gets an idea about something, they want nothing more than to explore it. They are also inventors and innovators. More than any other clan do the Earth Clansmen interact with the Cascadonians and Kadessi. They work well as a clan on thier own, but often find kinship with the Water Clans due to thier shared interest in building and stability.
No clan is as unpredictable as the Air Clan. Said to wield powerful magic, members of the Air Clan are often revered; however, they are difficult to find. Until recently the Air Clans were spread to far and so thin, that most Heasteans would go thier whole lives without ever seeing one. Recently (in the last fifty years or so), they have been recruited by Water Clan members to join the Frozen Flame tribe.
