[Quiet Man Cometh]

The attacking creatures are currently beyond the ken of trisphee history and as such, are not known yet, though perhaps something more might make itself known, or suspected, in the future. ;).

To echo some of Sheol's replies, the events here are connected to the ongoing story that is the Trisphee universe. Often times there will appear to be unanswered questions that will be adressed later. It never hurts to mention such things though. Some will be answered with patience, and others we may genuinely have missed, though we certainly try to cover all relevant holes even to event. :)
