For those of you interested, here's the lowdown on where the weapons came from in the FFXIII trilogy.
- Blazefire Saber: Obviously, Lightning's classic gunblade. Unlike traditional gunblades in the FF series, her's folds up from sword mode to actually transform into a gun. It is in gun mode that the weapon can be stored.
- Vega Knuckles: You would think this would be Snow's weapon, but Snow actually fights barehanded and beefs up his attack through emblems, which are symbols on the back of his coat. Vega is actually the name of one of Sazh's pair of pistols, and here they've been converted into...Gun-Horas? Here's hoping they actually shoot!
- L'Cie Bardiche: A bardiche constructed in the shape of the crystal pillar created by Ragnarok in the end of FFXIII, to hold up Cocoon and prevent its fall after the death of the Fal'Cie Orphan.Â
- Bladed Lance: Fang's signature hunting lance. In FFXIII, it split into a 3 sectioned sansetsukon. Aside from that, nothing too special about it, save how iconic the weapon is.
- Star Seeker: One of two weapons from FFXIII-2, this one belongs to Sera. In the game, it transformed between a bow and a sword, and was stored in Sword form (I think). I hope they repeat this in ARR, as the Relic weapon for the Bard folds up into a Harp when stored (please tell me I'm not the only person who noticed this).
- Binding Rod: Vanille's weapon, which was like some sort of hellish fishing rod. The forked ends would detach and dig into the enemy...It was pretty brutal. In ARR, it's a mere wand. Le sigh.
- Mog's Staff: Exactly what it says on the tin, kupo!  This belonged to the NPC Mog in FFXIII-2, who never actually participated in combat...Unless you count the fact that he actually transformed into Sera's Star Seeker. Regardless, this is the first time this staff has ever seen combat.
- Grimoire Wing: This is the stupidest thing I have ever seen. The concept is thus: They took Hope's boomerang (yes...a boomerang) from FFXIII, multiplied it, and slapped them all together and called the resulting monstrosity a BOOK. Yes, this is the Tome weapon for all you Summoners and Scholars. Aren't you special~
