New Skyrim DLC Rumours

"Bethesda's parent company, Zenimax media, have just trade marked the term 'Hearth Fire' leading to rumours of a possible future DLC release.
In the land of Skyrim, there are books containing knowledge of 'Hearth Fire', an ability to use a soul energy to raise the dead and conjure magical weapons. Skyrim already features many undead nasties, including draugrs and skeletal dragons, so it is entirely possible that we might soon encounter the horrors of this 'Hearth Fire' magic. Or perhaps the Dovahkiin will be able to master the ancient spells for their own gain?
Just remember one thing, Necromancy is only for naughty girls and boys!"
