Hell The Blade of Imprisonment

Hell is one of the God Blades. No confirmed details. The only mention of it is in a 500 year old document that described it being used in Chrom. The location in which it was said to be used is now a barren wasteland in which it is impossible for any sort of organism to thrive. Its abilities are said to relate to the manipulation of poison.
