A World Tree Sapling... As If There's Such a World Tree

[Core Room]

Thanks to the lord offering up sacrifices, the library dungeon… no, the fuel-storehouse dungeon had accumulated more than enough energy.

Then one day, the Dungeon Master happened to notice that its secretary Marie was holding a potted plant.

"Marie-san, what's that?"

"A World Tree sapling."

"World Tree?"

"An Asura's brain may be more efficient than an ordinary human's, but even so, memory capacity has its limits. And so I require what you might call an 'external memory device.' A plant's 'other self,' or rather its 'true body,' has no brain, so the memory density is low. But its advantage is that records committed to the trunk are never 'forgotten.'"

"I think I follow, and I think I don't… Wait, that potted plant is the rosemary plant?"

"That's right. It's an innate ability of tree-type Asura."

It means she can have a tree for a true body. That, and nothing more. It is not a World Tree.

"A World Tree is supposed to be the kind of tree that reaches all the way up to heaven, right? And rosemary, as I recall, is a shrub about two meters tall."

To belabor the point yet again, this world has neither the metric system nor the International System of Units. Some dungeons are, in their very design, built to metric, though.

"That isn't a problem, I should think… Probably."

Being short is a feature.
