The question was more one of where it gets the resources to grow like that. My bad for wording it incorrectly. I've asked it before but normally it gets buried under the avalanche of people with problems about Victoire.

Are the beds essentially giant mana vacuums that draw in the surrounding ambient magical energy or is it more of a biological thing?

Edit: Gaaaaaaaash dan it BC. I'm trying to go for non-hostile learning here.
