It was a particularly boring day at Sans' sentry station in Snowdin Falls. After the fall of Asgore, everything went quiet. No-one knew what to do. The monsters just meandered around. Toriel, the sweetheart, really tried. But it hadn't been the same. Sans had heard she ordered the destruction of every golden flower from the Ruins to New Home, and honestly? He didn't blame her. Losing Asriel so long ago had been one thing, but losing Asgore too? Sure, she hated the guy's guts and way of dealing with things but deep down the loss struck a chord within her. And so there aren't many flowers in the Underground anymore, no more signs of Asgore or Chara. The reign of Toriel had begun, but the monsters just couldn't find the DETERMINATION to carry on.
Sans sat back in his chair, flicked a little snow off of the front desk and twiddled his bony little thumbs.
