-They might obstruct wormholes, depending on exactly how they work. I'd say assume yes. You just get there by flying down from orbit. It is possible to get to the surface of Caelmare with flying ships, but just quite difficult (smaller ones will have an easier time of it).

-Haven't really thought too much about the exact composition of the resources on either planet. Water is definitely a thing on both planets, seeing as they have oceans (and Caelmare is almost fully covered in water). Hydrogen exists, and can also be extracted from water. As for food, Caelmare will be mostly without (maybe some edible algae or something) and colonies will have to depend on supply ships, but Tenelapis is likely to have some edible stuff since I plan for there to be native creatures (although half of it is probably as likely to eat you as the other way around).

-Yep, submarines would be pretty strong. Missiles would still work fine, but would have to all be quite low-flying so as not to hit the ceiling. Ballistic missiles would have trouble though, and VLS might have to be recalibrated a bit so that the missiles don't go so high on the initial launch.
