Tracking as in following a trail might work for both Ziotea and Rodion -- might be how they figured out where the other was as kids, but only could do it for each other.  Tracking tracking...eh, I don't see that being something she'd ever have any particular interest in, unless someone said she should.  So I really don't care one way or the other.  Just sensing, however, she almost certainly can do, and with a pretty good radius.  Of course it's always easier to sense familiar signatures, and then extremely different ones (like, say, demons or something).  Sensing someone supporting an aegis might be hard to do unless you're in sensing range of the the caster -- the aegis itself is hard to pick up at the edges.  *thinking*  I imagine individuals have different signatures with different strengths -- and most likely warpriests are trained to conceal their own, at least to some extent?

Sorry for the delay; had to have a lengthy conversation with my scanner about how it's supposed to scan things, and how I know it doesn't have ink but it's not getting ink and it needs to scan my arts anyhow.  x.x  This thing has such an attitude.
