for talking about current and future content, not back-&-forth about the light and void & bloody Yrel, there's a whole lore sub-forum for the constant bickering/debating on that sort of thing.
If there is any evidence, at all, a leak, or something in the game files, that points to light/void being the next expac or, I dunno, a new model for Yrel in the game-flies then sure, debate away. as it stands, there's as much chance its pirate-y than voidlight, & I don't see 10 pages of people arguing about whether or not the Bloodsail Buccaneers are good, or evil, or greedy.
That said, if the next expansion is light & void themed, those Scarlet Crusade items though. Loved the lore behind them. especially light's wrath.
