Zecharias Mnemosyne lived in the Backrooms for longer than he could remember. He's definitely not human, but no one knows what he could potentially be in spite of his human appearance. Many people had arrived in the Backrooms, but those who had seen Zecharias had never came back alive. He's a gentleman, polite and neat. However, he does have possessive tendencies towards anyone he sees as a potential 'muse' to him, someone he can truly love.
