Lord Solar Macharius

Lord Solar Macharius was the Lord Commander Solar who drove a crusade to the galactic edge in seven years and then discovered that even his armies had a place they would not follow. Donia raised a governor's heir. Terra made him the youngest Solar. The Halo Stars finished the argument.

He took nearly a thousand worlds, outran his own supply of nerve, and died on the way home. Officially it was jungle fever. Unofficially it was an assassin and a cover-up the Administratum still prefers. The Macharian Heresy was what his generals did with the map once he was gone.

The Ministorum made him a saint. The Guard still uses the name as a dare. His shrine world is Macharia, which was Donia first.
