Graveyard

150 x 150 Humanity thrived until one day a 4th mine was discovered. Luck went against humanity and death started to follow. Graves were built to to honor the dead, however the fourth mine collapsed in on itself killing many. The graves of the dead poisoned the water that filled the land killing humans by the droves. The humans were unable to keep up with the ever increasing bodies and so they filled in the 4th mine. A mass human grave remains filing in the 4th mine. Centuries have past and the land has slowly begun to heal. As beavers it is our responsibility to bring life back to this land. What we should do with the now empty graves is up to you, however we will not allow them to be filled with Beaver bodies. We must stay alive so the poison does not return. Prove that we can surpass humanity.
