Trian Aeducan

Trian is the Dwarf Noble Warden's older brother and the first heir in the line to the throne of Orzammar.

Background
Trian is the eldest son of the dwarven king. He is the logical choice for an heir but as the dwarven city puts all potential successors for king to a vote at the assembly, his position is not guaranteed. You will only meet Trian if you begin your story with the dwarven Noble origin, but you will learn of him regardless of the origin story you choose as Trian is spoken of while your party is in Orzammar and you can listen to everyone's viewpoint on his story. You will learn that, much as he may want the position, Trian, is not the king or the people's choice for an heir to the throne in Orzammar. Gruff and self-assured, Trian is a difficult character to get to know much about and he is killed during your origin story leaving the remainder of his background a mystery.

Involvement
When first encountering Trian, the player gets into an argument with him, and later learns from Bhelen that Trian is conspiring to kill the main character.

When the player is sent into the Deep Roads to recover a family sheild, he is joined by two unknown soldiers and his second. Once they have retrieved the throne, while leaving the Deep Roads, they come across Trian's body. The player will approach the body to check Trian and shortly afterward, the king arrives with Bhelen.

Beytrayed by the two unknown soldiers, eluded to have been working with his brother Bhalen, the player is sent to prison for the murder of his brother and as punishment, he is released into the Deep Roads for his sentence.

Trian's involvement consists of simply being a pawn in Bhelan's game to ensure he ends up on the throne and through Trian's death he is able to get brother of his more suitable brothers out of the way for succession.
