@Critas: I wouldn't allow them as player characters, and I think I was too hasty with my previous post. Because of one tiny little problem - every Obsidiman after emerging from the Liferock spends about a hundred years communing in Dreaming with the Liferock and the other Obsidimen (those that returned to the Liferock for good, and those who merge with it at the time), and sharing their memories of the world. That would mean two things:
1. Liferocks have appeared recently, because the magic level is just right? Oh well, the first Obsidimen should appear in about a hundred years.
2. They. Know. Too. Much.
EDIT: And 3 Any Obsidiman character that emerges now is either a blank slate (less mentally developed than a child), or one of those who slept through the downtime in their Liferock, or on some distant metaplane, and thus they eat immortal elves for breakfast... or they would, if they weren't full-vegan, and quite benign and altruistic (as long as you don't insult and/or threaten their Brotherhood or Liferock).
@CanRay: Liferocks aren't any different from other rocks. It's their magical nature that makes them interesting. That means nobody mined them on purpose (untill now at least). But your comment gave me a lot of ideas for Obsidimen-related stuff in Shadowrun: Let's say some of them are there. Now what? They're basically a living, breathing elemental/metahuman hybrid. A dual natured, 'animal' and 'mineral' Radical Reagent waiting to be harvested. There was an 'obsidiman skin armor' in Earthdawn, and this is not the Age of Legends - in the Sixth World even humans fear of having their body chopped by some tanamous butcher, so the Obsidimen should be worth even more on the awakened black market.
