Second, I would like to reference an Alyn revival. Players on the board that was deleted by Laural have reclaimed their respective creations and placed them in other venues. It is imperative that if an Alyn revival is in the works, that only creations made by the players involved are utilized.
Things like Karanda, Venway, the Warlock Order, Gardennia, and various other creations should not be utilized without proper consent by their respective creators.
As I will not be utilizing Krythal in any of my creations, it would be excellent not to utilize Dreadslays, the Mutiny alliance, the Abyss, Chaos Fields, Ruin, etc.
I know we're all creative people, so there shouldn't need to be any overlap in roleplays if the players in the roleplays didn't create the material themselves. A good rule of thumb--if you didn't create it, don't use it. If a player on your board didn't create it, don't use it. And if you're not sure who created it, don't use it.
