Is there a singular source that explains more about why we care about Roxborough? I played back in 1e then picked up the game again a while into 5e, so I missed out on whatever documented him as being notable originally. (I've read about his weird survival and existence, and that he was a notable shareholder in Aztechnology and Universal Omnitech. But it sounds like that he is 'on the loose' again is a big deal, and I'd like to read up on why he is considered to be of such note).
Arguably he greatest hacker in the world, Roxy used to be a high-end corporate raider who got into a tussle with an asset of Dunklezahn back in the day over buying something, got furious when he wasn't able to acquire it, and lashed out in revenge. Depending on who you believe, he unleashed the Crash Virus itself, which brought the world to its knees. (It very quickly went way, WAY out of his control, but no one alive knows that he is connected to it and can back that claim up.) ... that virus, of course, killed Alice Heffner, and the eGhost, Alice, is based off of her brain. (If it was her actual ghost, haunting teh Matrix, a shard of teh Crash virus that became sentient and based itself off of her, or something else entirely has neer been revealed.) ... unfortunately for Roxy, he also developed a unique, and rathe rhorrible, genetic condition which resulted first in him being bed riden, then worse, before finally being moved into a giant vat where his body just ... unravelled. His mind managed to survive, even as his body turned into a bunch of fillament and jelly, and he manage dto get a datajack implanted into his, let's say mass? which gave him access to teh Matrix as it was created. He's been on teh Matrix for 24 hours a day (even when asleep, he's jacked in) since Day 0 of the Matrix existing, and due to this, and the money he's pumped into his tech, he's arguably the greatest Decker in teh world.
He's also ruthless and immoral, and has been hungry for both a cure, and revenge, ever since his "Boxing". He's nearly gotten out several times, but Alicehad always been lurking in the background, undercutting his escape attempts. His most infamous was in trying to be implanted into Ryan Mercury's body (Part of teh DragonHeart trilogy, which gives you most of his backstory), but Alice was able to stop that and is quite happy to see him tortured and suffer.
When Alice died (or "died" depening on your reading, more on that in 10 AIs), Roxy no longer had an active agent as skilled at teh Matrix as him working to block his every move, but was also cut off for the Matrix for the first time when teh Second Crash happened. Once he got back online, he was free to start solving his big problems.
He also needed to make money.
Roxy's infamously ephermeal with alliances, and while he had worked with Aztechnology in the past, their relationship had soured. He briefly got a controlling stake in teh Bank of Japan (which underwrites all teh the Japanacorps and should be utterly untouchable), but that quietly went away not long after he got it... it's assumed that some kind of deal was made, but no one knows what.
So he's been quietly lurking in his box, a corporate raider whose humanity has long since vanished, teh world's greatest hacker and a high level corporate raider who ignores all teh rules, Doing Things for a while. Him showing up in teh flesh out of nowhere has shaken a LOT of people (not the least of which is KAM, his ex-wife, and teh Smiling Bandit, who's currently hooked up with KAM), and there's wild speculation and just how that's possible.
(And it SHOULD have had a ton of fans speculating as well, but.)
