Awakening, it felt its mind clearer than ever, but something surprised it, a set of black boxes asking something it hadn't expected to wake up to.

Seeing that its Leechlings could evolve made it happy, but disturbed its mind as to where they got all the Mana required for these evolutions, quickly checking its status, it saw its Mana was full and realized what they'd done. It had given an order some time ago not to kill the blood-roots with their draining, so when they ran out of blood-roots, they must've gone and drained something which it hadn't said anything about not touching, namely the Titan core.
Bolting out of its room it's thought was confirmed when it spotted the five Leechlings latched onto the Titan core draining it of its Mana, making the Mana hurricane be occasionally sapped of Mana by the Titan core as its Mana drains. It wasn't concerned however and merely elated they were actually draining the Titan core and not the blood-roots around it, in large part due to the fact it knew the Titan core was unlikely to run out of any Mana with just five Leechlings draining from it.
Having confirmed all the blood-roots remained alive, it started thinking about which evolution to pick as its primary which would add it as an available monster permanently unlocking that evolution. It immediately discounted the first evolution for obvious reasons, looking more at the other three which were all excellent making it unsure as to what to pick, but it finally settled on making its Progenitor Leechling a Vitriolic Leeching Abomination, unlocking it as its available monster and made two Mana Fused Leechlings and two Storm Blood Mana Leechlings.
It was briefly surprised at earning an achievement, but welcomed it nonetheless as anything which helps its monsters helps it, as for the Fae? It couldn't care less about them right now as it didn't even know what the rest of them even were and only knew of Pixies which it thought of as pathetic considering one died from some rocks falling onto it and the other died by being drained by a barely awakened Dungeon Core. Namely itself, so its opinion of Pixies was the lowest it could be.
It turned off its train of thoughts as it began watching the evolutions which were in progress, it's attention was mostly focused on the Abomination that was evolving far differently than it imagined. Instead of becoming large, it turned slender growing to a height of three meters and looked like thousands of Leechlings constantly climbing over one another trying to reach the top. It had four glowing orange eyes in the formation of a square. Its eight arms were one and a half meters long each, and each had something that looked like blood-roots piercing out of their palms, their three revolting fingers coiling around them, making them look like a complete nightmare to any who would see them. Its appearance began finalizing as its body color turned darker then it had as a Leechling making it seem like it was melting away in the darkness, finally stopping at being barely visible as its four orange eyes glowed as a fatal distraction to any who met them.
As the Abomination's evolution finished, the Core looked over the other Leechlings not seeing much of a difference except for the Mana Fused Leechlings which were glowing a soft pale blue light from their body being oddly enticing to the eyes. As for the Storm Blood Mana Leechlings, their color changed a bit from black to dark red, with streaks of yellow in the pattern of lightning bolts going across their body.
It told the four Leechlings to return to feasting on the Titan core hoping to make their next evolutions as excellent as these were. The Abomination, however, slunk away submerging itself in the pond leaving only its head above the surface as its eyes scanned for prey.
With its Mana full the Core expanded its domain over the rest of the Titan core area only stopping occasionally to let its Mana regenerate, and while it was doing one of these breaks, it discovered a hole in the wall behind the Titan core likely leading to more of the cave. It finished taking the entire Titan core's cave under its control and brought its sight before the hole leading into a new cave for it to explore and expand.
