Tenacity

Elves against Tevinter Emperium

And Codex note from DA:I:

“…Without the halla, there would be no Dalish. The second thing you must understand about the halla is that you cannot force a halla to do something against her will. I have heard tales of shemlen who come across herds and attempt to capture the halla, using ropes and bridles. Many shemlen have died impaled on horns as a result of this foolishness. Never forget that the halla once bore our knights into battle. The fierce blood of a warrior still runs through her veins and she would sooner fight to the death than demean herself. Like the Dalish, the halla are proud. A halla knows who she is, and will tolerate no being that tells her that she is less.” (Adara, halla-tender of the Ralaferin clan, to her apprentice)
