I wish they would bring this back... It did not make any sense that they left this out, especially since some Draugr are supposed to be encased in it... Dang lore breakers

From the video tho, the normal bow looked to be a Dragon Bone one... Let's hope they added Dragon Bone/Scale weapons to Blacksmithing.
Lore breakers? Stahlrim is unique to Solsthiem. It was created specifically to protect the bodies of the dead warriors who couldn't be returned to Skyrim, therefore it has no place in Skyrim itself.
I wonder if the Dragon Bone weapons will be better or worse than Daedric like how the armor is, after its been tempered to max level.
Also I would like to see some Aedric weapons or armor if they exist in the lore. Can anyone confirm this?
Lords Mail and the Chrysamere are the only artifacts I think can be traced to an Aedric Origin. Boots of the Apostle, Ice Blade of the Monarch, Ring of the Wind, and several other artifacts may also be considered, given their importance in the Imperial Cult quests of Morrowind, but their Pre-Morrowind lore doesn't necessarily link them to any of the Nine Divines.
Obviously the Crusader's Relics are all Aedric artifacts as well. I'm unsure of how these are entered into the game lore though. Acknowledgements in Skyrim exist, but I don't know if they were ever intended to be placed in the series again.
As for new Materials for Dawnguard, I wouldn't mind seeing Shadowweave (TES Mobile) and Mithril (Daggerfall, Oblivion).
