This is the level 15 Guild of Shadows Epic.
After speaking with your class trainer in Camelot:
[Step #1] Seek out Captain Rhodri at the Snowdonia Border Keep in Snowdonia Fortress.
[Step #2] Seek out Elrigh. It is said he Travels from inn to inn within the Black Mountains. Mention to him your interest of the [locals] within Barfog.
I found Elrigh in North Black Mountains inside Snowdonia Station, upstairs. /Say locals to him and he will start to talk.
[Step #3] Locate Andri inside of Camelot. He frequents the Bars there. Speak to him of [Barfog] and the [Renegade] guards.
I bought a ticket to East Camelot for the stable guy at Snowdonia Station to speed things up. I found him in the bar near the Defenders of Albion Guild. Go in the East Camelot Gate. Go forward past the guildhouse and the bar is on the left at the 90 degree turn. Andri is in the tavern called "The Stone" in Camelot (loc= 23600,20000). Andri is upstairs on the second floor. You need to /say renegade to him to get him to begin talking.
[Step #4]Return to Captain Rhodri at Snowdonia Border keep in Snowdonia Fortress. Inform him of the [Renegade] and of [Sir Dillus].
I bought a ticket from the stable guy at the East side of Camelot to take me back to Snowdonia Station, and ran the rest of the way. Once at the Fortress I told Captain Rhodri of the renengade and of Sir Dillus when prompted by the Captain.
Return to him yet again once you reach lvl 20 and achieve the title of Spy and he will tell you what to do next.
