I am the one has nothing to do with the Inquisitor.
It's from Origins and is an Elvhen song, about Elves. The one in Inquisition is a translation of the original old Elvhen lyrics.
Why would the HoF have a song? A character who doesn't even appear in the game! Harding plays a vital role in the Inquisition as one of the lead scouts, and hangs around near the tavern where the bard plays. It makes sense they would know each other and write a song. Why would she write a song about someone completely unrelated, who she never met, who doesn't even appear in the game.
Well she didn't meet Samson too and she wrote a song of him, I have to admit I didn't thought about the fact that she is only singing things that are related to the moment, but still, how exactly there is not any song for the others heroes?l, or more bards?
Harding, Leliana, Cullen, Josephine, their work is totally overrated, they don't do ANYTHING. But they have songs, Leliana two in fact if we count trespasser song. The final fight with Corypheous you just need yourself and 3 companion more.
The song of Trespasser making a hero every companion is exaggerated too.
It sucks the fact that our character save the world/part of it and they aren't recognized, calling them "Hero of Ferelden" and "Champion of Kirkwall" isn't enough. The same happens in Trespasser, no one respect your character and you have to act like you were submissive and obedient.
