Helio Imperium

The Helio Imperium is a location frequently mentioned by Davion. Stonehall plans to conquer the Helio Imperium. Something happened in this place, which involved Lina and Davion. There is a "Shoehorn" in this place, where a person that resembles the Alchemist (either referring to Razzil or the ogre, the latter made a cameo appearance in Dota: Dragon's Blood ) lives in.

In Dragon's Blood, Drysi briefly mentions the Helio Imperium when she confronts Luna and her Dark Moon troops. She recalls that they were sold out to the Helio Imperium by Luna, possibly giving some context on Luna's betrayal towards Drysi.

Speculation

 * Helio derives from the old greek "Ἥλιος" (Hḗlios), meaning "sun". The word imperium means "absolute power" or "kingly power". This may suggest that the Helio Imperium has something to do with the Solar Throne, the seat of power that Mirana was in line to hold before she abdicated to the Dark Moon Order.
