Hopefully that clears things up for everyone then. If not, then we still have time to ask questions since the encounter won't happen for a decent amount of time I'm assuming.
A little information about Theophilus and "Powerful Souls" to clear things up. I would very much, in a perfect world, like for Lore to be discovered In-character with as little exposition as possible. Unfortunately we don't have the benefit of item descriptions to help us with this. So I guess we'll have to rely on some NPC exposition to help explain things. Keeping true to the nature of choices, it is going to be up to our characters whether we're interested in hearing these tales.
I guess what I'm trying to say is that, we could quite possibly go through the roleplay literally just wandering around until we run into bosses and not really question why they are there. Every boss will leave behind it's powerful soul. We can't really read the item description of a soul, since it won't have one. However, we can do many other things with the soul. For instance, the Soul of Theophilus. We could consume the soul to gain extra power for ourselves, or perhaps we might come across a certain NPC who will offer us powerful weapons/trinkets in exchange for powerful souls. Maybe there will be an NPC like Ciaran, who requested Artorias' soul, that will kindly ask us for his Soul and in exchange for our charity offer us something of value.
I want there to be many options, and I kind of want there to be this weird uneasy feeling amongst our characters when we make decisions like this of "Did I just do the right thing?" or "Was there perhaps a better use for this Soul/item?". You know, that feeling you get when you decide to do something in-game and it kinda just turns around and bites you later because of it.
Without spoiling too much, let's just say that there will be a specific NPC that can be found after the first boss fight and before the Hellkite drake that offers us insightful knowledge on rare souls/items provided we pay them humanity. This will probably lead to gaps in knowledge amongst our group. For instance, Aghast, a Darkwraith has no trouble scrounging up humanity to offer in exchange for valuable information. However someone like Delwyn, whose humanity is fading slowly, might be more reluctant and choose to hold onto his humanity. Of coarse if someone in the group does pay the price, they can always share their knowledge with the others.
Idk I hope I'm making sense. If it doesn't feel like a good idea then please let me know. I'm just trying to re-create this feeling of choices that the game somewhat had. I'm a little reluctant to have an NPC act as an "Exposition Vendor" of sorts. Perhaps instead of one specific NPC, each Soul can only be explained by a certain NPC that already exists; making it our job to find them ourselves.
