Major Spoiler warning for the ending of Veilguard
But...I think they really had a missed opportunity, in killing off Harding or Davrin at the penultimate mission, they really should've kept them both alive(With Hardingwhich you send her to lead the second team, because Titan Magic, somehow Harding reacting negatively to the creation of the Red Lyrium Blade would shock Ghilinain long enough for her let go of Lucanis and then he attacks, and then Harding seemingly is injured and lost(she is captured just like your second party member choice. This causes her to be Blighted being a mini boss you fight and then free, she is not blighted but was instead responding in pure rage to anything and everything and then she and say Neve help you out against Elgarnan in the last leg, because Elgarnan guess tries to will the Blight back and is failing at it.
So then when confronting Solas, and redeeming him, he says he will go to soothe the Titans pain. Here Lace can offer herself up to go and soothe it, in completing her personal quest with either rage or calm, she says she can best understand their pain and needs to be the one to go and do this. Thus fulfilling her Destiny in typical Chantry fashion, chants a bit of the chant to herself.
Solas being long lived is made to promise her to find a way to bring the Veil down safely if it needs to come down one day, and she'll work on soothing the Titans.
There, that's my ending.
In fact, even if you choose Davrin, so long as you have him as a Hero of The Veilguard Status, then he lives, and Harding gets captured because Ghilinain registers her as the bigger threat.
Like, who else but Harding, the voice of the Titans, not a Deep road Dwarf, but a Surfacer, one entirely disconnected from the mainstream culture of Orzammar Dwarves and Surfacer Castes and Merchants. She was a homely farm girl growing up as the one dwarf in a human village, and she joined up because she wanted to protect her home. Plus with all the elf root she grows, she wants to soothe pain, and if need be taken out the thing or person causing the pain. So either in rage or calm, she still goes to soothe the Titans. The only thing that would change is her tone towards Solas.
