Bryan "No timed effects" Gregory - Bryan didn't actually work on Scions, but the core mechanics from Pathways were largely developed from his work, and as such Scions gained a huge benefit from his wisdom.
John "30 Effects" Pariury - JP has the amazing ability to pare down reams of concept work into a few concise paragraphs that are both amazingly complex and amazingly simple at the same time. I don't know how many people have played multiple systems and said that Pathways/Scions was the easiest to learn while still maintaining a variety of options for play. Most of that is directly attributed to JP's influences. Those influences guided the Scions team and even though JP wasn't involved with Scions his presence can still be felt in it.
Tony "Packet Guy" Parisi - Tony has the amazing ability to take anything I assign and get it done right. The first time. With no complaining. In some cases with amazing turnaround time. Tony is my right-hand guy on the development team and it's very rare for me to make decisions without consulting him first.
Marissa "Empress of World" Roush - Not so much in Pathways, but if Religion is the core of Scions, Riss is the core of the Religion. She's not a rules person, but she makes the game. She pretty much single-handedly developed the entire religion system and helped with numerous other plot related issues. Riss's work is what changes Scions from a medieval LARP with awesome rules into the unique game that it is.
Paul "Band Geek" Iverson - Single handedly responsible for Scions Bards, along with a bunch of other stuff. But definitely Bards. I've got to admit I was against Bards for a number of reasons, but Paul stuck with it, pushed it, and figured out ways to make it work. Thanks for being pushy.
Aaron "Web Monkey" Burke - Aka my secretary. Aaron is another one of those "just get it done" guys. He takes an insane amount of reference email and turns it into the rulebook that everyone sees. He's also the last line of defense against the evil typo and is personally responsible for saving us from some fairly major disasters. He's also the guy who tells me what to do, what we're missing, and we're finding he's got a groovy knack for rules too.
Chris "who?" Fisher - The server admin, my right-hand guy in real life. Fisher keeps everything running, all the time. 2am and I don't have email? Guess who gets a call. And he doesn't even play. If he wasn't keeping our network functioning, we wouldn't have the resources we do to keep development moving as fast as it is.. I can't tell you what an incredible aid the forum software and email communications are to the development process.
