So this thoery is that the mycelium from Hermitcraft Season 7 is the skulk that infects Cub in the Hermits and Empires crossover.
So skulk. It spreads. It infects people, enviornments and objects. Ever since its release from the deep dark two years ago it has dispersed itself into every world and uncharted realm, and proliferated into the minds of the curious and wandering. Similar to corrosive fungi or mould. And so is mycelium. A type of fungal threads that also acts in a similar manner to skulk but more passively. And so that's why mycelium might be the ancestor to skulk. Take Hermitcraft Season 7, the Mycelium War. The mycelium began to spread when the core block was surrounded by grass. Slowly corrupting the green surface which enraged the Mayor to create HEP as an attempt to uproot the infectious fungi but, resulting in the Mycelium Resistance to counterattack HEP's efforts. Resulting in the Mycelium War that ended in a minigame with the Mycelium Resistance reigning victorious.
But it was left to rot and wither after the season's end. Finding it's way into the damp, dark caves where it evolved into this monstrous fungi that feasted upon the deaths of organisms to spread and conquer back to the light of the surface. Thats's when a certain branch of sculk crept its way to the foggy surface of the mangrove. Crawling its inky veins to infect the surrounding enviornment. Secluded by the misty fog where it was able to broad and multiply until a curious scientist, exploring the uncharted mangrove stumbled upon the cluster of sculk. Entranced by the promises of knowledge and power, the sculk was able to spread. Fulfilling its dream of reaching the sunlight once again with the help of the human vessel. Until a witch with magical capabilities subdued the corruption fungi and it was banished back into the caverns. Never returning to see it so desperately wanted, the light of day.
