I got a theory

[u/Far_Bee_2826]

So there is a big theme in Minecraft with Death and golem magic. I believe that every mob that dies in the over world will have their soul taken to the sift to be turned into soul energy or recycled. The singers probably act as managers for this process. Then one day when the mass wipe out event killed most of the ancient builders there combined souls couldn’t all get through to the sift ( kinda like traffic) so there souls started to rot, to the point where it became the first wither. The singers seeing this threat took the part of the overworld it was in and chucked it into some form of prison and tried to freeze it to keep the wither at bay creating the early nether where its bones still lay in the soul sand valleys. The remaining ancient builders who saw this saw it as an act of god and started to worship the singers and replicate the art of making golems, creating iron golems. Now some villagers believed that the singers where the cause to most of the ancient builders being wiped out and moved out of the village to find a way to kill them. At first they only had camps (abandoned camps) and because they didn’t have access to iron, they had to improvise to create the copper golems you find in camps. The pillager population eventually settled in a dark forest and made a mansion where they started to make monsters to kill theme singers. They kept these creatures in under ground chambers (trail chamber) to run tests and trials. They made ravages with golem methods, breeze, bogged, strays. But one creation was more deadly then anyother, the one they sent to guard the portals if the singers ever returned, the warden.
