Dwarven fans rejoice! While we may be entering the "Season of the Dragon" you could also argue that we are entering the "Season of the Dwarf!"
We're getting a TON of new Dwarven things soon, revealed in PTS Notes and Data-mining, including a
new house! Finally!

The Frostvault Chasm is a Medium (200 Furnishing Slot/400 with ESO+ Furnishing Slot) House located in Western Eastmarch. While not the biggest place to stuff your Dwarven loot, it's still sizable inside! The Chasm itself is easily as big, if not bigger than Manor sized houses, so you don't have to worry about working with too much space to fill while still having the impression of a massive home! There's already previews of the place online.
And we're getting a new furnishing pack!

There's a bunch of items in here that have been in Dwemer ruins, but never available to players, especially that massive forge, which I'm betting is an ACTUAL forge!
Then there's two new Weapon Style packs coming, AND a special Shield Style!

The Engine Guardian Style Pack (Presumably releasing along with the Undaunted Head and Shoulders Style pages)

And the "Dwarven Remnant" Style Items, which could potentially be Crown Crate items for the upcoming "Dragonscale Crates," like the Voriplasm Style items in the Xanmeer Crates.

AND the Spellbreaker Shield Style (Seems to part of an "Elder Scrolls Artifacts" Pack). Spellbreaker was originally a Dwarven "Tower Shield" that was taken and modified by Peryite.
We're also getting two new pets:

First is a "Carnelian Theodolite" Pet which is an excellent alternative to the Dwarven Theodolite pet if you don't have access to the Morrowind region, or can't be bothered to assemble it's Runebox. We're also getting a "Icebound Dwarven Spider" Pet, which is the reward for beating the new Frostvault dungeon on Veteran (Dangit I guess I have to finally try to beat a DLC Group Dungeon). I don't have a picture, but I think it's safe to assume it will be a Blue-ish Dwarven Spider.
There's even some new cosmetics!

There's Dwarven Centurion Tattoos/Markings

And Dwarven Geometry Tattoos/Marking

AND Dwarven Sprocket Earrings!
I'm so excited for all of this!
