Lapis' tower was well above any clouds, maybe even at that level. Which would indicate that the tower stretched farther than the highest forming clouds which would be at 40-ish thousand feet above sea level. Even at lower levels, about 7-8 thousand feet ASL, normal humans can already feel the effects of altitude sickness (shortage of oxygen). At that height, the normal oxygen levels would be at =~80% (100% at sea level). Even at 30 thousand feet ASL the oxygen levels would be at more or less 30%. So at Lapis' tower, you could imagine the extrmely small amount of oxygen in that level of the atmosphere. Any normal human would've died from hypoxia in mere minutes (if the vacuum doesn't kill them first).
