New companion Justice revealed:

Not all the denizens of the Fade identify with darker emotions like rage and pride. Some embody the nobler qualities found in humanity: faith, hope, compassion, and justice. Justice is not a name, it is an identity. A victim of magic gone awry, Justice has been torn from the Fade against his will and trapped in the body of a dead Grey Warden. Lost and disoriented, he seeks a guide to help make sense of this alien world and demonstrate what it means to be human.

Architect enemy revealed, will be familiar for those of us who read the calling.

The Architect is the first darkspawn to develop a will of his own--an unusual outcast who seems not to be subject to the call of the Old Gods, nor to the other darkspawn compulsions. But although he is highly intelligent, the Architect has little understanding of humanity. Treating him as anything other than what he is–a darkspawn–would be folly.

Wending woods revealed

The Wending Wood is an area of forested slopes and lush greenery, divided by the trade route known as the Pilgrim's Path -- named for the faithful devotees of Andraste who walk that very road to reach Amaranthine, and who have left ancient relics scattered about the wood to honor Andraste and the Maker. For centuries, the wood was known as a place of breathtaking beauty and tranquility, but things have changed in recent months: a clan of Dalish elves has set up camp within the wood, and their proximity to human villages is making the locals uneasy. Even worse, roaming bands of darkspawn have been seen in the wood, undoubtedly gathering for some nefarious purpose. For now, the people of Amaranthine can only pray that whatever troubles the Wending Wood passes soon.

Kal hirol revealed

The dwarven fortress of Kal'Hirol was long known as a center of learning for the smith caste. Its workshops are where Paragon Hirol conceived his famous improvements to golem resilience and power, and where Hirol's favorite student developed a method for storing refined lyrium that is still used today. These breakthroughs brought Kal'Hirol great prosperity; its passageway are said to have glittered with gold and silver. But the fall of Kal'Hirol is shrouded in mystery. All that is known is that the fortress's elite one day showed up at Orzammar's great doors, exhausted and in despair over the loss of their home.
