Who uses mana?

Could you please elaborate on the question, 'Who uses mana?'" I'm genuinely curious to understand the context in which this term is being used. Is it in reference to a specific cryptocurrency or blockchain project? Or perhaps it's related to a gaming environment where mana serves as a resource? I'm also wondering if you're inquiring about the types of individuals or entities that typically utilize mana, or if you're seeking information on the practical applications of mana in various settings. Could you provide more details so I can better address your question?
