The Dragonborn stared at the vortex of swirling purple haze and asked his companion; "So, what is the Soul Cairn?"
Serana crossed her arms, "It's a plane of existence where souls go once they've been soul-trapped. Or, so I've been told." She shrugged, "Ever soul-trapped someone before?"
The courtyard of the Thalmor Embassy was littered with fallen High Elf mages, soldiers and archers. The Dragonborn tucked his bow away and hopped down from the rock he'd been using as a sniper position. "Yes! All my black soul gems are filled!"
The Dragonborn shook his head to Serana's question, "Not often…"
Author's Notes: My brother always feels bad trapping humans in soul games, so all his black soul gems go to the Thalmor...hehehe
And it is possible to shoot arrows through some of the gaps in the wall of the Embassy and kill the Thalmor. They are trapped inside if you haven't done the quest there and can only shoot magic and arrows back at you. But, if you are good with the bow you can snipe from far away.
