Several years after the end of the Second Calamity.
In those years, Yale didn't return from that dimension, so it was unknown what happened to him, but based on their plans, Alrein and Kroh decided that probably he managed to get a tie and both, Yale and the Dimensional God, had their consciousness erased.
Of course, they had already told everything to Yale's family, and the mood had been quite gloomy all those years. They knew that Yale did it to save the multiverse, but they were still unable to believe that Yale didn't exist anymore.
"I am sure he is just trapped in that dimension or somewhere else after obtaining the victory. I can't believe that he died!"
It was strange seeing Lina so hot-blooded in the past, but since Yale disappeared, it was quite usual when she was speaking with Alrein and Kroh. Of course, they knew that Yale couldn't die, but losing his consciousness could be considered something with a similar effect.
