The information is correct. The Original quest was given to me by Glorfindel in Rivendell. That starts you to Calenglad and then on these 3 sub-parts of the original. Glorfindel is by the waterfall in the Northeast part of Rivendell.
This quest is part of a 3 part quest given from Calenglad at Tinnudir called Loyalty's Proof. Once given Loyalty's Proof quest, you talk to three other npcs in Tinnudir that each give you a quest. This one, and 2 other quest called Washed up on the Shores and They Spy from the Heights. There was a quest from Trollshaw called "Calenglad Remained" that sent me to talk to Calenglad. I believe you have to do this first before getting the Loyalty's Proof quest.
