Yeah, spelljammer has magic sea-going vessels (mostly) sailing between crystalline spheres (which had planets or whatever inside) kinda' things. Not necessarily different dimensions, iirc, but close enough in concept to match. Similar fiction plays around with star-gate sorta' stuff or magic equivalent of wormholes, sometimes doing stuff like ripping off chunks of planets/dimensions and chucking them into the distance. And then you have, y'know. Nanoha, which goes high level magi-tek style nonsense. There's all sorts of stuff to play with, heh.
Though depending on the setting dealing with barren planets can be pretty easy, if perhaps riskier. Just rip open a hole to a hell dimension or a few elemental planes or somethin' and clean up the mess once it's done infesting the planet
...also yeah some sort of galaxy scale arcanum 4x could be friggin' crazy interesting. Especially the interplay between magic and tech lean, writ solar system plus scale.
Aboard Dwarf Corvette 99-EchoCaptain Broddok, the gruff yet practical commander of the ship, straightens his space tunic before addressing the assembled crew.
"Alright gentledwarves... We're coming up on the coordinates of the enemy mage-vessel. It's a massive spell-slinging fortress with reinforced warding against enemy incursion and the hazards of space itself. Intelligence says it's crewed by no fewer than a hundred battlemages, all of them bristling with magical energy and bad tempers."
He inhales deeply, continuing.
"I needn't tell you how dangerous this encounter is going to be, and how horribly outmatched our wee ship would be in a fair fight against this monstrosity. Luckily, we've got a secret weapon."
He reaches into the weapons crate at his feet, grunting slightly as he hefts a large silver oblong and holds it aloft.
"This is the X-27 torpedo. It's a highly classified design, and the most expensive piece of equipment currently on this ship. It's equipped with twin-linked gyroscopic navigational safeguards, 360 degrees of thruster adjustment, a self-contained molten salt atomic power plant, a backup Bose-Tesla quantum generator coil in case of primary power failure, five guidance computers with tandem processing, a miniature class 3 biohazard research laboratory, and it runs DOOM."
The gathered crewmembers gasped with hushed awe. Then Lt. Tagrum, the weapons officer, raised his scarred and weathered hand.
"What kind of payload is it equipped with?"
"None. And it doesn't need one. The sheer technological alignment of this thing should disrupt any magical influence within 200 meters. Our plan is to maneuver past the initial enemy barrage, and then fire the X-27 directly into the heart of their shields. The spells and glyphs holding the whole damn calamity together should unravel in moments, and the spellship will collapse into pieces as its crew are sucked into space."
The crew cheered. Broddok concealed a smile of his own beneath the curly mane of his beard, and dismissed the crew with a curt nod. They all had their orders, all that remained was to see if their plan was good enough... or, perhaps, insane enough.
