Basically, we had a very long while in the UCA where things kinda got bad - we had months at a time with no show, then random people began hosting their own shows every week. Things had gotten really stale storylinewise too, and no one was really trying to shake things up, so we decided to do a mass reboot of the UCA. I held a ruin where the entire gimmick was that THERE WAS A BOMB, and everyone was locked inside. This bomb gave everyone kayfabe amnesia, and everything beforehand was forgotten about entirely (except the recordbooks). This served well, as gave newcomers a perfect place to join in, since they didn't have to learn about a ton of feud plots to start.
It also gave me sole control over ruin somehow
