According to the DUNGEONS & DRAGONS Companion-level rules, a
land-owning magic-user is called a "Magist" (MAY-jist), and a wandering
magic-user is known as a "Magus" (MAY-jus).
Most Wizard regents in the BIRTHRIGHT rules that I know of do just sell
their services and realm spells, or use the Alchemy realm spell. Mine,
however, (being the greedy sod that she is) has recently been looking in
to her own guild holdings and trade routes.
