Seheron

Seheron is an island nation directly north of the Tevinter Imperium. The capital is also called Seheron.

Background
Seheron is the western Qunari island. Sten is apparently from Seheron, as he comments "I miss the smells of Seheron, tea and incense and the sea." Fenris may also be from the island, as he tells Hawke that's where he was told he is from.

One of the dialogue options with Sten, while in camp, leads to more details about enemies that attacked Seheron, presumably the Tevinters, who are known to be at war with the Qunari. While the Qunari have a firm grip on Par Vollen, their control of Seheron has been in dispute since they claimed Seheron from the Tevinter Imperium sixty years ago. Dialogue with Fenris confirms that it is indeed the Tevinters that have been vying unsuccessfully for the island for the past sixty years.

Many elven slaves in Seheron have willingly converted to the Qun and now hold office within Qunari ranks and anti-Tevinter sentiment even among the humans runs high. Because the Tevinters never signed the Llomerryn Accords, the Qunari invasion continues in Seheron. Seheron is still "kabethari" to the Qunari, literally "those who need to be taught."

As of the present day, the Qunari hold control of the island under heavy resistance from Tevinter and at least some of the native population. A rebel group called the Fog Warriors exists that opposes both Qunari and Tevinter control of the island.
