I feel it really depends just how close to the end of this part of the campaign are we? Because this feels like a sufficiently close end since I’m guessing the big scary tentacle thing is more or less the final boss (though tbh I thought Cyanwrath was the big boss of this cave). So an old character like Orchid could sacrifice themselves so we create a vacancy for the new character to slide in. Or at least that’s how I figured we could do this.
