@Reaper Devil

The other two logged in earlier on the last day.

" 37 out of 41 people have quit, and though the remaining three remained as guild members in name, Momonga could not recall the last time that they’d shown up with the exception of today."

Therefore all 4 last members were online on the last day and just logged out at different times, except for Ainz who didnt logged out.

IF someone of them show up in the new world, the other should be there too, or have been there.

Maybe the two player of the 13 heroes were his comrades and after he learned their names, he resurrect them somehow and the problems begin.

Maybe HeroHero is somewhere too, but have problems in gathering info and travel because he is a slime.

There are quite some ways to include his former comrades into the story. (even if i doubt such a thing)
