After narrowly surviving an invasion of her dungeon by some seriously dangerous Elves, Sandra needs to recover from having all of her defending constructs destroyed in the process. With the bulk of her forces lost while shattering the Core of a Reptile Classification dungeon, the merchant-turned-Dungeon Core is feeling a little vulnerable. Luckily, she has Violet, a Gnome Apprentice Enchanter, to help her get things back to normal. With Felbar, another Gnome that has decades of experience culling Dungeon Monsters, and Echo, an Elf that mistakenly got tangled up with Sandra and her dungeon, now awake from their Visitor Bond-induced comas, she can finally work on improving her relationship with the Gnomes and Elves by providing them with much-needed supplies. Unfortunately, during her time of recovery and looking into crafting new things with her recent access to Enchanting, she neglected to keep an eye on the dungeons around her Area of Influence. With the Gnomes no longer there to cull the Undead Classification dungeon near their destroyed village, Sandra scrambles to get ahead of its rapid expansion – and potential threat to the Dwarves to the north. But even if she manages to destroy the Undead Classification Core, should she stop there? Now that is quite the dilemma… This Dungeon Core story contains LitRPG/GameLit elements such as statistics and leveling and a heavy crafting emphasis. No profanity and no harems.
