User blog comment:Solmonster, the Daily Phantom/The messed-up continuity of the Thanos Trilogy/@comment-24812000-20170510221138

I read somewhere that it actually does take place during Infinity. Keep in mind that the Thanos trilogy was written by Starlin, whereas Infinity was mostly by Hickman. And that the trilogy was written over an expanse of around 3 years and after the Infinity event. This means that Thanos as a character can be portrayed differently, and that the latter, like all later works, can find ways to tie into previous continuity such as Infinity. Specifically, I remember it saying that the Thanos trilogy should be read after New Avengers #8. That means this all can happen before he becomes trapped in amber.

And again, this is just what I remember from somewhere.
