Hidalgo Bolt was a mage appearing in Mortal Coil and Death Bringer. He is in his fifties and has a crush on both China Sorrows and Valkyrie Cain. He is described as a "cute", agile man with a permanent distracted look in his eyes. He looks to be twenty or so.
He likely had a relative that fought in the War, as he was too young to have done it himself. He is a frequent patron of China's library and was possessed by a Remnant in the outbreak. He attempted to stop her and almost succeeded before she smashed a bookcase into him.
