Although they don't have many weapons due to being pacifists, their technical tech is appareled.
Un-FTL: A massive metal (2x10) horn that has magic stored in it. It requires 'Arcane Crystals' (Power) And Quantum Machunks (FTL Fuel) to use, but will give an entire ship 100% efficiency. You cannot place anything in front of it.
HARMONY CANNON: A cannon powered by six modules (You need all six to power the weapon.) that fires an unstoppable beam of Rainbow Death to destroy ships.
Hive armor: Developed by changelings, this stuff is cheap and strong, but takes up space. (2x2 minimum size.)
Arcane Reactor: Pulls magic from the sun, condensing it into crystal chunks. It works fast, but is large. (2x4)
Arcane Charger: (A small, weak Reactor, 1x2) reactor that makes Crystals slower.
More ideas will come later.
