Not much is known about the organization, its history or responsibilities, but it does appear that they act as a check and balance to the power of the Templar Order, acting in a secretive, investigative and interrogative capacity to root out corruption and protect the Chantry from internal and external threats, much like the inquisition in real life. They also may become involved in the hunting of particularly cunning apostates. Templars fear and despise the Seekers, as they must usually involve themselves when the templars are failing in their duties.
In the framing story for Dragon Age II, the Seekers have captured the dwarf Varric in the hopes of learning more about Hawke, the Champion of Kirkwall to put and end to the current world-spanning war. They also appear to be interested in the Warden as well.
- The eyes on the Seekers symbol looks the Eye of Providence, which is an important symbol to many real world religions including Egyptian Mythology, Buddhism and Christianity (often with the addition of an enclosing triangle). The symbol is one of the most well-known symbols used by the Freemasons for whom it serves as a reminder that God is always watching over them. The most well-known use of the eye however is its depiction on the reverse side of the Great Seal of the United States where it is framed by the words "Annuit cœptis" meaning "He approves (or has approved) [our] undertaking(s)".
- In the Dragon Age universe, the symbol of the Seekers may represent the watchful eye of the Maker or the Andrastian Chantry. Similar symbols have also been used in previous Bioware titles such as the Eye of Neverwinter sigil from the Neverwinter Nights series (used on the cover of the case and used to distinguish the Neverwinter Knights).
- During Act 3 in the docks, you can see fortifications in the now closed-off Qunari Compound where a symbol of (presumably) the Seekers is visible, foreshadowing their interest in the events at Kirkwall.
- In Witch Hunt, an ancient Orlesian book in the Circle Tower titled Of Hammers And Witches: A History may mention the Seekers. The book contains depictions of "men in robes [who] tremble before figures bearing an ominous symbol of a black eye in a sunburst."
