Without further ado, the winner is [b]Prince of Seraphs[/b], and the [b]two credits[/b] are his.  Your idea was original and well-explained, as well as given flavorful folklore.  Second place (and [b]one credit[/b]) goes to [b]Scarifar[/b] for the naginata Aeran.  Even if this entry reaches beyond the barrier into magic, I did not expressly prohibit magic, and it is plain that a lot of effort went into this.  The Bleeding Edge longsword crafted by Kaithas honestly seemed rather Mary Sue-ish, if a weapon can be so.  For a weapon whose unique ability is healing, only the bloodiest and most impressive things appear in its history, without any real specifics to focus them on.  While the Sagitta was freaking awesome as a concept, Guess Who, well...let's say that historians aren't the only ones looking upon this giant cannon with skepticism.

Thank you all for entering.  PrinceOfSeraphs will be managing the next challenge.  Good luck!
