Him dying means the Haven dies. I hope this results in them only using the Haven for when they have to rest and to keep food and stuff. That way him and his harem can move during the day, and if he dies there's no one in the Haven to die with him. Him letting his Harem's family and the military stay in the Haven while he's out on Earth for "safety" is pretty ballsy; he or they don't know that he's our protagonist, if he dies all their family dies..
Well, it can be solved by you, author, deciding that a "failsafe" exists, so that if our MC, and therefore Haven dies, they all have x time to evacuate to Earth through a portal that will spawn (though, can't the Pillars of other faction do this as well then? Which would make the loss of lives due to Havens fall harder to explain). Otherwise I can't see people being happy or accepting that he's out roaming about and risking all their lives. As the military, I'd threaten his harem/their family to keep him locked up in the Haven
Whose Tracy again? Also nice development so far. Though it's looks like he's making a Haven to early and won't get to explore the Mana filled world. I feel like when he makes the Haven, even though he finds a way back to explore the world and get stronger. He won't be allowed because he's tied to the Haven and if he dies, they'll all die. That's why I hate being a leader. To much responsibility.😩
