Kulviss

The Kulviss are the parasitic species that cause Molgri's Tumour.

Description
The Kulviss appear as dark, gelatinous masses when manifested in reality. These parasites manifest in colonies that take specific shapes, with individual Kulviss being mostly a gas giant sized formless blob of translucent material. The entities themselves display no true self awareness or sapience, instead behaving similarly to colonies of single celled organisms. Individual Kulviss are relatively fragile in comparison to most other life forms of their power, often being destroyed by phenomena such as supernova or wandering black holes.

History
The first encounter the makers of the Weave had with the Kulviss came in the initial expansion of the Weave. The initial wave of explorers whom scouted out the nearby realities came across the parasites feeding and reproducing, observing them from afar before reporting their findings back. Several more expeditions were sent after these explorers, until they had determined the organisms to be non-sapient and overall mindless after prolonged observation of their behaviour and the unresponsiveness they exhibited whenever attempts at communication were made. During this time, the Kulviss began encroaching on Weave held territory. What followed was culling of the Kulviss infestations near the Weave, with the entire species being marked with a cull order due to the highly detrimental effects they had on realities.

The regular culls of Kulviss continued until the shattering of the Weave, whereupon those in around Weave held territory rapidly multiplied without being kept in check. Entire universal clusters were destroyed in the ensuing chaos and regions in the Void became infested with the organisms. These infestations would not be kept in check until the First War of Reclamation, where millions expeditionary fleets destroyed swarms in former Weave territory. To the present day, expeditionary and mercenary fleets are sent out to cull Kulviss infestations wherever they are spotted.

Life Cycle
Kulviss reproduction and maturation is unusual in the regions of the Weave and its remnants. The species require a host reality to reproduce, earning them a desgination as a parasitic threat. Kulviss begin their life in an embryonic stage after a universe is infected by several adult forms. When Kulviss manifest in realities, the phenomenon known as Molgri's Tumour occurs. Molgri's Tumours appear as expanding regions of space-time that do not follow their surrounding's laws of physics and actively cannibalise the rest of a reality's fabric. Molgri's Tumours are the exhibited effects of incubating these embryonic Kulviss. Over time, the infected reality undergoes a cascade collapse as the rest of the uninfected regions are destabilised by the proliferating tumour, before ceasing to exist in its entirety.

As the infected reality collapses, the larval stage of the Kulviss emerges from the remains of Molgri's Tumours as they too collapse. These Kulviss mature in the Void, feeding off the remains of the dead reality and tumours. The adult Kulviss move on, ready to repeat the cycle on the next universe.

Relationships
The Kulviss are at best regarded as a pest in more developed multiversal civilisations and at worst treated as an existential threat by weaker ones. Kulviss colonies and swarms are marked for extermination when detected, with fleets of drones used to carry out cullings in both realities and the Void. One of the duties carried out by drone swarms and their commanders from the Negentropic Union is the pre-emptive extermination of colonies and swarms ahead of civilian personnel when searching new universes for habitation.
