There's some speculation circulating about the death of the scions, which if it holds any weight at all, is something I personally don't want to see happen.

Here's why on a couple points; supposedly in the 2.5 trailer video we see the scions engaged in several events of battle, climax' hinting towards devastation among the group, and a send off from Minfillia tied to a bow of loneliness.
In 1.0, for those of us that can remember (which for me was way back in SEP 2010), the first PC's/NPC's after creating your character that we meet (as part of the Gridania scenario) are Palpymo and Eda. Two characters that have been a part of my lore for more than four years. I can't say I'm too fond of them, but they have a place in my heart. "You don't know what you have until it's gone", next thing I know I'm watching a part of me vanish from my lore and my heart sinks.

While I can't offer a more personal speculation how 2.55 might foray from the above, I don't want the see the above happen any time soon. I don't need another Aerith event, lol.
