Visionary skills summarise aspects like precognitive dreams, visions, and prophecies. They seem often a bit reserved towards other characters. Although or maybe because they seem to have deeper insights into their own psyche. And maybe on other’s as well? Perhaps visionaries even found a shortcut to something like a collective mind? But that is just pure speculation. On the other hand, visionaries can be very enthusiastic characters as well. Might depend on what they saw in their last vision, one is tempted to say.
feAther, m0rl0ck, and Feenja would all categorise themselves as visionaries.
Fl!ck saw herself as one as well, so it is only a plausible theory that false or misinterpreted visions lead her astray.
