The sword should actualy be surprisingly simple to create.
For those that understand blender and nifscope AND want to give it a shot - this is how:
I bet you've seen flaming swords allready. It's a simple thing realy. An effect plane is attached to the sword, Always rotated towards the camera and along the sword axis. The effect plane cycles trough a few "difuse maps". Simple pictures of the flame, with the transparency controlled by the alpha chanel packed in nicely in a dds file.
So just fire up your modeling program of choice, model the hilt, attach a plane to it and name it effectplane01. Then create the texture, a simple blured rectangle with rounded edges should work fine, use a similar smaller rounded edges rectangle to make the middle part black again. Copy this into the alpha changel and export as a dds(with a DXT5 compression). Then save it as a dds one more time but discard the alpha changel (just save it with a DXT1 compression) and name the file "yournamehere_g.dds". You want the sword to glow, right? So that's a glow map. If you think yourself good then you can create several such textures with dissorted edges to make the sword look like it's pulsating. And the rest is just putting it together in nifscope. I suggest copying everything from a flame sword, pasting in your mesh and textures, deleting the rest and changing the ninode entries.
