April Fools actually originated from a prank played on a french king, so yes, pranks are absolutely SMA.
Hey, I'm not saying I hated the prank. I just didn't find it funny.
OOC, it was fairly obvious it was a prank, so I don't think it really fooled anyone (other than maybe a few newbs). IC, though... Are you saying the daimons pranked us? A noble pranking another can be SMA, sure, but the daimons playing "peek-a-boo" with portals on us, that's just silly.
What I was saying is that acting as if the portals hadn't poped up would not be SMA, especially after all the people that reacted did so. My character interpreted the events as the barrier between worlds having been weakened on that day, perhaps because of the portal stones adventurers used, but that (thankfully) the barriers resisted and regained their strength when the day ended.
