Well back in the day, Maruyama had originally planned to end it  in 18 volumes or so. However he also said that if fans countinue to support it, he has enough material for up to 50 volumes if he tried.

Now plans have certainly changed, for one thing both vol 10 as well as 13 were not planned as they were made due to him realising he needed additional information to keep the story in check. Also Kadakowa the one's who publish his story might also pressure him to countinue it as it is a big series both in Japan and the West right now.

However let's just say he still is planning the orginal ending he wanted with a few + volumes. Most likely it would end with the Conquering of the Slane Theocracy and become the supreme overlord of all the human nations in this region. It did seem that way in the beginning at least.
