As stated above, RP Scenarios that result in the creation/destruction/exchange of assets in the Darkness database, as enforced and implemented by Admins will not happen.
White Scenarios are still structured and award CP for GMs and XP for players. Assets are neither created nor destroyed, and no other aspect of your character as they exist in Darkness can be affected (no HP boosts, no death, etc.). They are considered Canon, so of course, usual rules apply for seeking permission from groups and individuals to include & use planets, NPCs, etc which are under their purview. Again, they'd only be included on an IC/Canon basis, and nothing in Darkness would be affected.
All that said, there's nothing to stop Players from coming together and organizing a White Scenario with stakes (the phrase was coined elsewhere as a "Pink Scenario"). E.G. utilizing game mechanics that are within their control to translate the consequences of the Scenario into Darkness. (e.g. making OOC agreements to makeover assets based on events that occur in an RP, or to destroy the said assets (recycling, I guess), or even more simply to agree to make Canon the destruction of certain assets for use in GNS postings, without affecting the database itself). The fundamental point to keep in mind though that it is entirely as between players - there would be no outsider or Admin enforcement of the agreement. If someone chose to reneg on the Agreement, it lies completely with the players to deal with it - No Admin or ASIM or Otherwise will alter Darkness or do Anything to enforce the Agreement.
