Dragon Age: The Gathering Dark
Russel's old employer, now his seneschal, killed by the party.
Ansel used to run a logging business of his own but Trewin bought him out and offered him a job afterwards. Ansel is a good factor but he hates playing second fiddle to his old competitor. His release was negotiated by Ser Russel who he now works for as Seneschal (of sorts). He also manages the trade in venison from the hunting lodge.
Ansel was mind controlled by Blacktail through some ritual and was killed by the party who mistook him for the apostate.
