ComStar is a politically influential, quasi-religious organization which maintains a monopoly over the HyperPulse Generators, which are crucial to interstellar communication; the threat of a communications blackout, also known as an interdiction, made ComStar a significant power within the Inner Sphere. Its currency, the C-bill, is considered the safest among the circulating currencies. They profess to be neutral to the politics of the Inner Sphere; this is known by most political leaders to be false, as every Successor State has felt the meddling hand of ComStar in their affairs at one point or another.
Jerome Blake was a religious figure to ComStar; oaths such as "By the blessed Blake" or epithets such as "Blake's Blood!" are not uncommon. Jerome Blake was the founder of ComStar, after the Star League fell, and is considered by those within ComStar to be the savior of the Inner Sphere.
