Malos viator Caelestis

Just you wait - Origin
Malos viator Caelestis is a direct descendant of Thordan zos Caelestis whose whereabouts are currently unknown, with only some selected people actually knowing his direct location, with his presence not being felt anywhere near close to Eryr. As he has been kept from the world, so has the world been kept from him, with him knowing nothing of what the world is like save for some selected things his mother told him before she too passed away, causing him to kill all the Custodia in the Royal Palace, and 3 Royal Blades in a rampage due to his mother's passing - The only figure to even teach him love. Ever since then, his location has been changed to a place where he may harm no one at all, and be forever sealed.

While very little is known about Malos, some of the old files about this incident do describe this "nameless inmate" as someone possessed of not just one, but two Murmurs for seemingly unknown reasons. He was also born with the ability to feel the Concepts around him, something that should be only adquired by those who reach into the Depths and return.

Murmur: Command (Name given by the Archives of the incident, not real name)
Command is described as an ability that allows the user to manipulate the space and people around him through commands he admisters verbally. The range of this is undetermined, but he was able to bend the walls and generate spikes to impale several guards by simply stating "Earth: Impale" and has killed several of the officers by simply telling them "Die" - Though this seems to have some limitations, as he does not use this quite often.

Murmur: Vaccum Blade (Name given by the Archives of the incident, not real name)
Vaccum Blade is described as an ability that allows the user to quickly slash at a region on which a circle of slashes will appear - Said circle will then implode, erasing all the space and matter within it, or alteast sending it to an unknown location. This ability was used to cleanly erase a large portion of the Palace, which is why we had to mention it in the news to begin with. We do not known the range of these capabilities, but it seems to be quite deadly.
