AETHERVOX, SHIPBOARD (Telephonoscope)
An Aethervox (Voice of Space) is a “magic mirror” that allows communication between ships by projecting signals through the etheric plane. These devices are powered in part by purified ectoplasm that acts as a sort of telepathic version of radio waves and wifi. This requires that the ships be within 500 miles of each other (20 miles within a planetary atmosphere). An aethervox is only capable of “real time” communication only, though specialized “gest tubes” are occasionally used to store conversations and images for use with an Aethervox.
Furthermore, using an Aethervox as the material component for Scrying grants the user advantage if the person or object being searched for is on an asteroid or planet that the ship is orbiting. This item is located on the bridge, typically in front of the Helm. When speaking to another vessel, the Aethervox creates an image of the speaker that appears on the mirror. The device itself is the size of a cabinet (medium) and is permanently attuned to a specific Helm.
Range: 500 miles (20 miles in atmosphere)
Hit Points: 18
These vulcanite sealed glass jars contain the glowing green ectoplasmic energies of ghosts gleaned from the etheric plane. When used with an Aethervox, these tubes can store a message of up to 10 minutes in length. Such messages include sound and visuals that are shown on the Aethervox screen and speaking box. Cost: 20 gp
Creating Geist Tubes
Spellcasters wishing to make their own geist tubes need only collect ectoplasm in a glass jar which is sealed with vulcanite. This process requires a successful arcana check and an alchemist’s lab. Success creates 1d4 jars. To complete the process magic mouth must be cast on each jar.
A NOTE ON ECTOPLASM
Ectoplasm is the slimy goo left from the interaction of spirit world, or ethereal space, creatures and magic with the regular, or prime material world. Ectoplasm enhances Necromancy, boosting duration and range by 50% per pint/litre. However, carrying around more than 10 pints/litres of it attracts undead. Unrefined Ectoplasm is sticky, ranging from holds 5 pound objects for 1 hour, and can be found in the trail of many undead and some aberrations.
Wealthy individuals and Imperial Military Officers occasionally have possession of stationary Aethervox devices with which they maintain communication with distant persons. This is far more common in the core systems such as Alpha Centauri and wealthy trade hubs such as Istari in the Ukdah (ι Hydra) star system. Technomancers schooled in the Invisible College make great use of Aethervox lectures stored in Geist Tubes or broadcast from lecture halls far from students. Often, Imperial outposts will maintain an Aethervox for important communications for use by Officers and important officials.
