It may not be completely obvious from above, BUT!
Your first optional boss is ready!
The way this will work is, in order to elect challenging the boss, someone (SOMEONE WHO IS NOT ME) will have to get a UNANIMOUS VOTE from the rest of the players, and return to me saying that you would like to challenge the boss.
From there, the fight and all will be done in spoilers at the bottom of normal posts, so as to have the fight going on at an undetermined time and place relative to the current mission, while we continue to play along the mission itself.
AFter the boss is defeated, I will put the rewards into the current mission's debriefing.
When you wish to act against the boss, just do as I do, and put "Boss action" and then spoiler tag the rest of it, as to not disrupt the current mission.
Canonically, the optional boss will have been challenged and defeated (Hopefully) between missions.
Edit: Forgot to mention. For Optional bosses, you get to pick ONE(1) additional party member from the NPC pool to accompany you. Keep in mind that Juliet is active from 8 AM to Midnight, with Byrd being active from then to 8 AM, and you WILL NOT know the time when you fight the boss ahead of time.
Also note that Thirteen isn't in the pool yet.
Hey there! Can I give you a hand?
