When the trial run of "Investigation Task. Far" appeared.
The knights in line immediately started discussing, and about five minutes passed before a few knight teams headed to the affiliated building, but these knights also held the idea of taking a look first and might not necessarily accept the task.
It's not about how difficult the investigation task itself is.
It is solely about the distance.
The area ≤100km around the Holy City is also known as the "Sub-Security Zone".
This area is constantly under the perception of prophets and authors, frequently conducting knight activities (mainly investigations, secondary training), and is within controllable range. The danger will generally not exceed the critical value and definitely will not trigger a 'chain event'.
However, areas >100km exceed a large part of the prophets' and authors' perception range.
The area has not been subjected to hazard removal for a long time and only occasional expeditions have been conducted.
