Lord Guy

Lord Guy will be present during the Oaths of Fealty quest at Vigil's Keep. He is standing at the brazier, in the company of Lady Morag. If the Warden-Commander is Orlesian, and they talk to him during the ceremony at Vigil's Keep, Lord Guy is intoxicated, and expresses discontent with what he considers an Orlesian attempt to rule Ferelden again while his father died trying to liberate the kingdom. The Commander can persuade him that forgiving one's enemies is the best way to give peace a chance, or use intimidation to make him stop talking.

If the Commander doesn't choose this dialogue or fails in the persuasion/intimidation check (Expert Coercion skill is needed), then he will be taken by the guards out of the Throne Room. Afterwards, the Commander will have to decide whether his drunken behavior should be ignored, punished or executed for his traitorous words.

Lord Guy is also part of the conspiracy against the Warden-Commmander and can be found and killed at the Old Stark's Farm.

Furthermore, if the Warden-Commander is Orlesian and the persuasion/intimidation dialogue choices failed or weren't selected or Lord Guy wasn't spoken at all during the ceremony, he will assume a more important role in the conspiracy provided that A Brewing Conspiracy hasn't been dealt with and wasn't executed; he will be responsible for instigating the peasants in The Peasant Revolution as well as directly participating in And You, Esmerelle? quest.
