Guild Wars 2

In Labyrinthine Cliffs there is a Sylvari merchant named Lonan. Nothing particularly interesting except once in a while he would greet the player with “Treesong go with you”.
Has this greeting always been here and it’s just extrememly rare. (I’ve never heard any Sylvari say this before) If not, who/what is Treesong?
Note: I’ve added a picture for those interested (Ignore the UI, I was quickly fidgeting to get the screen)

He’s probably refering to the song that the Pale Tree signs to her children to give them peace:

It has been quite a long time since I last heared it, it’s beautiful

It’s a standard male sylvari greeting. Nothing new to it. I don’t think Treesong is the song Fear Not This Night, but something more metaphorical, and likely akin to the Christian saying “may peace be with you” at the end of mass.
