I got my mods re-installed (just a few: the char icon and jammies - which look way brighter now - plus the amulet of power unfix) and what's the first thing I see upon loading up my latest Tanith save? The Descent is now available.
So, she went to the war table to get it set up, then headed to Undercroft for a major crafting spree. Tanith, Blackwall, Sera, and Bull all got new armor plus upgrades. Blackwall also got a new axe complete with master cleansing rune for taking out darkspawn faster (hopefully). Then she did a quick run-around Skyhold to talk to everyone (except Leliana*) and took her newly upgraded crew to the Storm Coast. I decided to take the long way there this time rather than quick-travel via the map or war table. Current game state is pre-Adamant, so Tanith doesn't yet know that Blackwall isn't really a Warden.
*Not sure why but I decided this game to never talk to Leliana. The only exceptions have been unavoidable cutscenes and turning in secrets at the ball. Somewhere along the way I realized this was not a good idea in a game where I recruited the templars, since it means I won't be able to activate any of the Calpernia story missions. Oh well....I don't really like her anyway. 
I was kinda hoping I still had a save from Dofni's game, where Blackwall's big reveal hadn't occurred yet, but sadly I don't. I wanted to see if anything happened, like, "don't worry, Blackwall's a warden and can save you from the taint, right Blackwall? Blackwall? Hey, where did he go?"

... can't wait to read about it in your PT. I should hopefully be done with Descent by then and can read about everyone's adventures.
I started making fan videos again! It's been since January/February. I haven't played the game since around then, either, but I was feeling inspired to go through my old recordings and put together a Solas romance video to this song by a band I just discovered (Straight Line Stitch) and really like. Enjoy!
So... last time you were here -- has it really been since
February? 
-- you were making Blackwall romance vids, and I couldn't watch them because I was playing through the Blackwall romance and didn't want to spoil it. Well, guess what?

I took a break from my actual Solasmance game in order to play the descent DLC, but... yeah.

I'm beginning to wonder if I will ever be able to watch one of your vids, heh. I'm kidding, I did go back and watch the Blackwall ones after I was finished that game and they're great.
