A piece of arcane machinery designed to create a spatial distortion field using six different sources of elemental magic power. In addition to the traditional earth, water, wind, and fire magics, the Drive also employs a source of radiant and necrotic energy.
While this sort of elaborate mechanism is not normally necessary for creating a planar portal, the swirling elemental energies on the boundaries of the Prismatic Vortex make it impossible to stabilize a portal otherwise.
The theory behind the Hexelemental Drive was known around the Gearspark Complex as the ‘Bunzinger Hypothesis’ due to its’ enthusiastic promotion by [[Dr. Bunzinger|Doctor Zacharias Bunzinger]] and the lukewarm reception it received from his contemporaries.
This re-invigorates [[Dr. Bunzinger|Doctor Zacharias Bunzinger]], leading him to request that the party seek out the magical artifacts necessary for its construction.
This rather cliché MacGuffin hunt has nevertheless yielded a number of intriguing artifacts
- The Heart of Shardmoon Castle, a corrupted Epochite Shard used to enable the sinister floating keep to cross space and time.
- The Iridescent Blade, the radiant crystalline sword that banished Shardmoon Castle into the Vortex, but that later gave rise to the rampancy of Iris Four.
- The Heart of Charybdis, a whirlpool-conjuring artifact that made the Lost Triad legendary.
- The Foundry Reactor Core, a powerful but otherwise typical shard of elemental fire direct from the elemental chaos itself.
