Temperature is not a solve everything fix but it might help. If it was -30C 243K out side and even 30C 303K inside the envelope that would provide a useful amount of lift. And you could make it warmer still. | |

And yes by all means if its fantasy then fill your boots! Alternatively you could introduce what I call "minimal magic", that is keep everything as per our world except for one thing (as bit like assuming lots of Xenon) but ensure that not physical laws are broken. I think I was reasonably successful when I tried it here: worldbuilding.stackexchange.com/questions/191893/… | |

That being said, it's a fantasy world, so - even though it should mostly still follow the laws of physic in order to maintain an internal consistency - simply declaring Xenon to be common is not a problem. I'm aware it probably doesn't make a whole lot of sense from a chemical point of view, but I'll take the artistic freedom approach here. Anyway, I'll look into the temperature option - might be worth a shot, provided the difference is notably (and not just +5% buoyancy or so) | |
