Hi and welcome
Good to see another new face
As for your question, I can't be 100% certain as Calico will know for sure, but as far as I'm aware The Superhuman Gambit quest is classed as a side quest so effectively at this point in time only the main quests, Those! and trouble on the home front have been completed and so, The Mechanist and the AntAgonizer will be battling it out as no one has been around to do their quest. Effectively the current time line would say that they would have progressed to being the crazies that they are and it wouldn't be before then....
Although...because intro posts (and well, any post really) don't have to be set at the same time as the rest of the threads, I guess you could put your characters starting story before they became The Mechanist and the AntAgonizer and then move her up to the current time afterwards, if that makes sense? I'm probably rambling, but it makes sense to me
It really depends on how you want to work it.
Anyway, don't worry about anything, it can all be worked in some way or another
And that is the end of my unnecessarily long winded answer
Looking forward to your posts!
