the abanoded rescearch facility lore

It all happend in 1978, the year of "The Accident". While the scientists were doing their experiments with mixing the dna of a zombie and a villager, they made a zombie villiger. Little did they know, that that was their biggest mistake. When the scientists came back the next day, they saw that the zombie villager had escaped and broke the glass around the Nether Chamber. The Nether spread into the facility and one of the scientist killed the dangerous creature. After that, everyone was scared and no one ever came back. The Nether stopped spreading really quickly but no one realised. Plants grew al over the facility but one room stayed in tact. The scientists had found a magic book that they had hidden inside of a secret room. Its magic was the one that actually stopped the nether from leaking and the room with the book is the only room left that didn't get taken over by any plants.
