Day of Return, Unknown
It appears there is a lapse in my memory that is preventing me from remembering what occurred recently. According to my journal entries, I was teleported to the Material Plane and explored for a while until I spoke with an entity that offered to return me to my expedition crew in exchange for the completion of a task. I do not recall any of this however, and neither do my expeditionary crewmembers. My team says that they watched by travel up the stairs of the building we were camped out in, and then a few seconds later watched me appear back on the main floor suddenly. This Between Plane is certainly special, and while it might be worth exploring more to find out what this entity that spoke to me is or what it wants, it also might be too dangerous and we should return home to ask advice from the elder. I will see what the team thinks.
