Radicalization is the blanket term for when a Caller and/or their following become problematic to the functioning of their faction through their beliefs, actions, or general incompatibility with the established norms of the Passage Lands. The process of radicalization is intensely studied. Scholars and administrators believe that they process starts with “problem Callers” or “Howlers” and there are two major pathways by which a Howler develops:

• Zealotry: Within any spiritual structure, fanaticism is inevitable in a small portion of the following. Ideally there are safe-guards to detect and neutralize these individuals through ostracization or literally eliminating them. Most second and first-gen Callers are technically zealots: they believe and defend their faiths with a disturbing passion that far exceeds that of a typical member of their faction. But this passion has been moulded through years of training and is considered safe to operate within a stable community. Some Howlers are Callers who are poorly trained. They either lack the necessary awareness to see the true purpose of their faiths or are so devout that they see no reason to involve their faction’s decision-making apparatus with its religion. Other times, Howlers weren’t even Callers to begin with, but rather zealots who assumed the position. 
• Disgruntlement: If zealots exist because of fundamental conditions within themselves, Disgruntled Howlers are the opposite. These are Callers who were stable and effective before an incident turned them against the rest of their faction. It could be continued abuse, literal abandonment, or any manner of events that makes a Caller “snap” and renounce their central duty.

Howlers go hand-in-hand with rebellions, secessions, and coups. When a normal Caller becomes a Howler within these movements varies greatly. Sometimes they are the instigator, taking on the roles of political and/or military leader. Other times they are following a maverick warlord or administrator. This raises questions about the complicitness of Howlers within the movements they participate in and the overall function of Callers within GT-A. Are Howlers really being treasonous by continuing to serve their local community, even if that community is engaged in treasonous activities? Do Callers have a responsibility to challenge inept or dangerous rulers? Can religious upheaval be a force for positive change? 

Howlers are further classified by the differences between their original faction’s ideology and the one that they preach. They are typically either “liberal” or “conservative” with all kinds of further descriptors for their stance on militarism, foreign involvement, and so on. Liberal and conservative, when used to discuss Callers have no relation to the actual political ideals behind the terms— instead, they are used relative to a Faction’s current state. Conservative Howlers advocate for a faction to return to an earlier state, often in the early 40’s or even late 30’s. A liberal Howler profess more extreme versions of a faction’s current trajectory. In reality, they are more of “traditionalist” and “futurist/accelerationist”, but the names stick. There is a third major kind of Howler: “Mystic”. These are Howlers who place an abnormally (Depending on their faction’s existing stance) heavy emphasis on the supernatural. This mysticism can include the Barrier-Pattern, V-Ronins, Singing Road, Formers, or even Pre-Burnout religions. In the mid 50’s onto the present day, Mystic Howlers are the most prevalent kind. 

Yet another kind of Howler is the “Screecher”. These individuals aren’t even technically Callers, as they do not originate from any pre-established church. Screechers make and propagate entirely new religions, which is extremely problematic in many ways.
