Germ

Description

The entity crawled along the caverns: an amalgamation of smaller beings. A hive mind. It thrived on staying with a living host.

It had hooks with which it latched onto the rough surfaces. Everywhere it went, it left parts of itself. Parts that started crawling on their own.

It existed only to fulfil a singular purpose: reproduce. It feasted on the soft tissues of its host. This caused the host to lose vital cognitive functions, and was thusly reduced to a singular goal also: consume, to feed the thing consuming it. A spiralling unbalance. Unnatural. Unending.
