My main adventure is None Pizza With Left Beef, but the one I'm really proud of is actually a bonus Q&A threadventure mirror called Ask Dylan. It's best read after completing the wintermission retcon route in left beef, for the sake of context.

The main adventure starts out as an in-setting (kinda) engineered epilogues food option, and then quickly dives into a completely different post-session world, exploring a breadth of what is possible beyond the limited expectations of homestuck as most know it, mostly with days and days of slice-of-life in order to introduce the setting and its new characters.

Ask Dylan show an entirely different side of things, from the point of view of the apparent antagonist, driven to boredom while waiting for left beef to resume updating (this was during a flash pause). Guests and other anomalies appear in his office to ask questions and cause mayhem. It is complete, and the plot of HyacinthHeld will draw directly from it.

Eventually I will return to working on left beef, but I've got a game to work on first. (don't expect updates for another year unless you can send a compelling command)
