I teleport to Falin. 'Are you okay? Where are they? Do you at least have some kind of sample for me to test?'

Sauriil teleport me and the Riders to Valenwood

Very well. Why?

We need to explore, find more clues to this, we need more men here.

I leave the temple and I start going back to Tamriel, specificaly to Sauriil.

Falin winced, "I'll live. As for a sample," She gustered to the still bubbling puddle, "Plenty there. Seems the ones in advanced stages turn into that when killed."

'Hm.' I take a vial and fill it with the liquid. 'I'll need a Daedra Heart, and some Nirn Root.'

"I saw a pond nearby that had a few Nirn Root growing around it. Noisy things. You're on your own for the Daedra heart."

I nod, and head toward the pond. I take the Nirnroot. Ah, and for the Daedra Heart.

I summon a Dremora, summon a Bound Sword and cut open its chest. I take the Heart from the corpse. As that happened Falin saw everything.

"Figured you'd just have one stored away." She shrugged, "Not that a neverending supply of fresh ones doesn't hurt." She rotated her shoulder and winced. "I heal much faster thanks to Y'ffre, why haven't these wounds healed already?"

'Corruption. Whoever caused is powerful.' I squeeze the Heart over the vial of Corruption. The mixed a few pedals of Nirnroot. 'Eyra, frey zey, genun zey fos vonum daar Vulom bo nol.'

A black mist rises into the air. I saw a purple sky, black pillars of stone and flashes of blue lightining. 'Of course! Coldharbour!'

Falin frowned. "He'd be the one to corrupt beings like this . . ." She looked at Sauriil, "but shouldn't he still be trapped in that soul gem Auri-el gave you?"

'It isn't him. No, something much more powerful. It's . . . Gods, no.' I stagger, 'But . . . that's impossible.'

"Sauriil? Are you okay?"

'No . . . I -- I don't understand. I killed him!' I felt an emotion I haven't felt since . . . then. Fear.
