The Nord announced that he'd made his decision, and Sindri arched a single dark eyebrow. Well done of him, she supposed, for not needing to dwell uselessly on the fate of his enemy. The battle axe he'd summoned— mage-work Sindri would have to look into when she had the time- raised, declaring his judgement to be in favour of execution. While not bothered by the spatter of blood nor death, Sindri stepped to the side and extended her arm, holding Brigit at length to give the man room to end a life. 

Instead, they were all called to pause by the dark elf, and all heads looked her way as the mage suggested capturing Brigit's soul in a gem. The idea didn't faze Sindri at all; magic had to be powered somehow, and she was certainly willing and able to do far worse to her enemies. However, her brief assumption that all were like-minded to her was short lived, as immediately, the Altmer (of course, the Altmer) voiced his vehement objections. 
Even from the poison-hued Argonian which, admittedly, surprised the Reachwoman. 

"While I've no issue with using her soul to power your weapons, I suppose they have valid points." She said, drawing Brigit toward her again, her muscles aching from holding the woman hostage. "We've a duty to perform together, and a move such as this will set a precedent for what sort of unit we are. One that we made not come back from. Especially not amidst the purpose set upon our shoulders."
Extending her arm again, Sindri nodded toward Sylruna. "I will ensure you get plenty of souls along the way. Plenty of hares, elk, and wolves to hunt."
