Silicon Mummy

Source Alien Archive 4 pg. 76
Deep in the lightless depths of countless worlds live murzzilats, amphibious mammals known for their grotesque contortions and ethereal vocalizations. Capable of both swimming and flight, these creatures are ungainly on land but well adapted to life in partially submerged tunnels and caverns, where their songs echo for miles in a haunting underground symphony.

A murzzilat has an oversized head with massive bulging eyes and a wide mouth it unhinges to swallow small prey whole. Green scales lined with dozens of powerful pectoral fins covers its elongated, shriveled body. Membranous wings protrude from its back, and six spindly limbs dangle down from its body, each ending in a sharp hook. Although these weak limbs can’t support its body weight, a murzzilat can shove them deep into cracks to drag small prey out of hiding or use them to latch onto large prey. An average murzzilat is 6 feet long and weighs 35 pounds.

While swimming, murzzilats fold their wings flat against their backs and fold their legs up under their bodies, propelling themselves through the water with their fins. The incredibly flexible creatures squeeze through narrow tunnels and cracks by contorting and twisting their bodies, displaying their internal organs, and popping their limbs in and out of joint. These adaptations enable murzzilats to escape from cave-ins and travel through tiny tunnels that creatures of their size typically couldn’t pass.

Murzzilats have scent glands along their backs, which they rub along stone to mark their territory. This overwhelmingly strong scent is long lasting but pleasing to most sentient species. Highly valued in the beauty and cleaning industries, the scent glands of a murzzilat fetch a high price on the black market and make poaching a profitable venture, particularly on Akiton and other planets with lax environmental regulations.

Incredibly vocal, murzzilats have a multitude of calls, cries, and songs. From clicking trills and deep bellows to haunting nocturnes and joyful refrains, their many songs echo throughout the tunnels and caverns they call home, both above and below water. Considered holy to some adherents of the goddess Shelyn, murzzilat songs have inspired artists throughout the Pact Worlds and beyond. Five years ago, a team of xenozoologists set out to catalog murzzilats’ songs, recording vocalizations from multiple worlds. Preliminary research from the ongoing study indicates murzzilats consistently add new vocalizations to their repertoires. Interested zoologists often seek to enlist the aid of locals and trustworthy explorers to track the evolution of the creatures’ songs.

Murzzilats find the death or theft of their young, called bantlings, incredibly distressing; such an occurrence causes them to enter a torpor for a prolonged period of time, refusing to sing for months on end. Although both parents mourn, the parent that birthed the bantling will follow the scent of the deceased or missing bantling for miles in search of its remains, going as far as to collect the leavings from a dangerous predator.

Special Abilities

Constructed Shell (Ex) For effects targeting creatures by type, a silicon mummy counts as both a construct and as undead (whichever type allows an ability to affect them for abilities that affect only one type, and whichever is worse for abilities that affect both types).
Silicon Casing (Ex) A silicon mummy’s protective exterior and nonfunctional organs limit critical damage; the mummy has a 25% chance to ignore the extra damage dealt by a critical hit and gains a +4 bonus to saves against critical hit effects.
Solar Battery (Ex) A silicon mummy can absorb solar energy in the form of Solar Reserve Points (SRP), which they can spend in place of Resolve Points. For every 8 hours a silicon mummy spends exposed to the light of a star, the mummy gains 1 SRP, to a maximum number of SRPs equal to one-third their CR (4 for a mummified prophet). For every week a silicon mummy absorbs no stellar energy, they lose 1 SRP. However, the mummy can intentionally enter a state of hibernation to lose only 1 point per 20 years, and although the mummy is aware of their surroundings and can fully animate as a move action, they are staggered for 1d4 hours afterward. As a swift action, a silicon mummy can expend 1 SRP to enhance either their next melee attack, ranged attack, or spell before the end of their turn. An enhanced attack gains a +2 circumstance bonus to its attack roll and deals an additional 3d6 damage if it hits. An enhanced spell increases the spell’s saving throw DC by 2.


Whether mummification involves storing bodies atop frigid peaks, interring them in deoxygenated environments, or carefully preserving them with chemicals and surgical care, most processes of mummification trace their roots back to archaic societies. With the development of advanced materials, the favored method now involves injecting specialized resins into a cadaver’s veins— afterward either replacing the body’s flesh with a silicon facsimile or sealing the body within a translucent silicon shell that shields them from the elements and decay. Although some request mummification as a symbolic gesture, others have developed techniques for sealing a creature’s soul within their body and animating them as an unliving, sentient being. These occult methods are carefully guarded by a handful of corporations and cults.

The most sophisticated reanimation rituals preserve nearly all of the original body’s memories, even allowing the soul to persist in a comfortable way that doesn’t drive the undead creature to embrace evil. Although some of these beings continue their previous lives in a less public capacity—interacting with polite society through the infosphere or intermediaries, or operating openly on planets like Eox—in many cases the silicon mummy withdraws from the living world entirely. Wealthy families occasionally shell out extraordinary sums to preserve a revered elder or beloved pet.

No matter the methodology, though, the complex mummification ritual doesn’t always go perfectly. Flawed procedures for creating an undead can result in a mummy with mere echoes of their former self, with the remainder of their persona replaced by insatiable rage, unshakable ennui, or empty compliance. Those undead that aren’t destroyed outright (or lost, if the mummy escapes the facility) can find roles as guardians or servants. Yet even bodies preserved for mundane burial occasionally animate spontaneously, often awakening in a combination of pain and confusion before haring off in desperate pursuit of justice or answers. Creatures accidentally mummified in industrial settings can also animate as silicon mummies. For example, an employee who tumbles into a vat during a preventable accident might arise and systematically murder their negligent supervisors. Unfortunately, rogue mummies aren’t always recognized as a threat thanks to their role in popular media, especially in several campy xenoarchaeology films over the past century that have inspired popular costumes worn to masquerades and specific holiday celebrations.

Silicon mummies retain enough control over their bodies to make subtle alterations to their blue-gray exteriors, rendering crude emotions and facial expressions. Furthermore, a mummy can modulate the opacity of their silicon exterior, either highlighting or obscuring the preserved veins or body within. However, the impermeable forms lack the vocal capacity to speak, instead gaining the ability to broadcast their thoughts telepathically.
