@Azarhal: The Executors, huh? Interesting and yes, mysterious. I pulled this from a Reddit post I found by "Myusha123":
"The Executors are mysterious representatives who speak "on behalf of powers across the sea", presumably entities from beyond the Amaranthine and Boeric Oceans. They are believed to be organized and maintain a number agents and resources across Thedas, but their motivations are unknown. They use as their symbol a downward-pointed triangle with two wavy lines drawn through it.
The Inquisition first learned of the existence of the Executors in 9:41 Dragon after their symbol is discovered marked in chalk at nearly every Inquisition outpost. Archivists were unable to identify the symbol in any records, but Inquisition agent Argent claimed to recognize the it from a ledger belonging to the Comtesse de Bayard. The Inquisitor had the options of getting the reclusive Comtesse to cooperate, or setting up a decoy outpost to capture whoever is making the symbols. Either approach connected the symbol with agents who spoke of "those across the seas".
The symbols did not reappear after they were removed. Leliana eliminated the Qunari as the most obvious suspects behind the marks, and concluded that someone with ties to "those across the seas" had an interest in the Inquisition. Although Leliana wanted to investigate further, Cullen dismissed it as pointless and argued the entire affair was best forgotten so they could focus on Corypheus.
If the Inquisitor deferred to Cullen:
Three Inquisition outposts along the Nevarran border were later found abandoned, yet with no sign of a struggle or looting. A message was left in each outpost:
We hold your Inquisition in high esteem. Thedas's present troubles are great, but you have the strength to meet and conquer them. More will come. We prepare for the day and hold vigil. Do not look for your men; do not mourn them. They have given themselves of their own free will to a higher cause. On behalf of powers across the sea, The Executors
If the Inquisitor deferred to Leliana:
After Leliana followed up on leads concerning "those across the sea", a message was sent directly to the Inquisitor:
Compliments to your spymaster. She is a resourceful woman. Once she traced our agent to Caimen Brea, the match was ruled in her favor. Tell Sister Leliana to call off her dogs. Save them for Corypheus. We suspect also that she has gotten all she can from Ser Helmuth. A caterpillar on a leaf does not know there is a forest about him. You will hear no more from us. Our intention was to watch, and we have seen enough. Corypheus threatens us all, and the Inquisition is Thedas's only hope for stopping him. Remember that, for the moment, we are not your enemy. As a gesture of goodwill, we share our knowledge. May it prove valuable in your coming battle.
On behalf of powers across the sea, The Executors"
