General Lachesis

Alchemist of the Soul
You have a plan to keep Conquest from being disqualified, and I'll help. I still want you to find Pestilence for me, but… I want Vaughn to pay too. He didn't do anything directly to me, but Vaughn reminds me of what it was like when I was alive. Wretches like him revel in the misery of others, and are rewarded for it. He's perfect for the Legion, and I should try to be too. We need to make him beg for mercy.

Alliance
Rayce wasn't the only one who approached me with bribes. They all promised to win the Reap and make a wish on my behalf. In exchange, I would tune their souls. I was expecting too much, which means I'll go back to searching for the Horseman of Pestilence. I will help you and Conquest win the Reap, and in exchange, you'll find Pestilence for me. Then… I can leave. I can sleep, and never get up.

Wish
What would I wished for if Rayce or another of my prospects won the Reap? It's a simple request. One that I thought would be fulfilled if I joined the Legion… but I'd prefer to keep it a secret. If you knew, I wouldn't be able to look you in the eye. Actually, I can't begin with. That's why I wear a mask… I have trouble maintaining eye contact during conversations. I don't mean to be disrespectful. It just happens.

Styx
The Legion's Generals oversee the five rivers of the Underworld. I am responsible for the largest. It's easy to hide in the River Styx- even the Ferryman has trouble tracking me down when I escape. Oh, escaping from what? I'm not looking to leave the Underworld. There's no point, I just want… silence. A place far away, where I can go knowing there are people who want me to come back.
