Man on an island, day 372

I Safely reach the other side and beach my raft. I expect a horde of villagers armed to the teeth to storm me but I am greeted with nothing but silence. I walk through the eerily quiet village...no voices, no shouting and no bodies! The huts have taken some damage but much less so than the village across the water. I open a hut door and I enter...everything has been left as it is. There is even food on the table and children's toys laying around. My senses are on razor's edge for any sound but nothing. I head over to the chief's hut and I remember the hit to the head I took there. I find nothing but a smear of blood in the main hall! Their all gone! just like that! I walk back to my raft while deep in thought and I make my way back across. Something big happened over there but what?
