"- Ethan leaves Arcadia and starts home. He automatically knows where his Home Realm is (the rules say so - so it is almost like an internal compass, like always knowing where the north reference point is). But he should also be able to concentrate on the Arcadian Door and know where that is too! Simply by switching the 'object of he desire', he should know whether it is left or right, near or far. So take that thinking one step further, the more realms that a Lord of Gossamer has visited, the more complete a Lord's 'mental map' is of the Stair. If Ethan thinks about Versais, he'll know which way to go; if he thinks about Arcadia, he'll know which way to go. If he thinks about a realm where there is a safe bed for the night (which is a generic concept, not a specific target), he can find that too.
- So now take that concept even further. Can Ethan pursue multiple targets simultaneously? For example, he's walking on the Stair, heading to find Lucien (who is a long way away); but he's also looking for targets of opportunity along the way. He is interested in any worlds where the sky is green (and according to Wayfinding, he would know if he passed a Door where that condition was met); he is also interested in meeting another friendly Lord of Gossamer on the Stair (so if it is possible to achieve that, he would also feel a vague calling to head in a particular direction), and perhaps even more obscure, let's say that he's looking for a place where he'll meet true love (ouch! that would require right person, right place, right time!) - so that's a conditional situation without a specific target. I can't see why a Lord of Gossamer could not do all of those things, which then makes things very interesting,
- Let's take Grant for example. He's going to the Royal Ball in Marindar where he is hoping to find a way of uncovering part of the plot against Marindar. If someone used Wayfinding to effectively 'progress the plot' and it is possible to do so, then Grant can use Wayfinding to find that situation - the right person, at the right time and the right place. Of course he could still say or do the wrong things and the opportunity would be lost; but …. hey!! …. that makes Wayfinding extremely powerful, and perhaps rightly so."

Eek.
"Safe bed for the night" predicts the future. Also eliminates the necessity of ordinary security precautions and the possibility of exciting ambushes.
"Find Lucien" You can find anybody. They can find you.
"Meeting another friendly Lord of Gossamer on the Stair" let's you know who is actually friendly and who is dissembling. You could also, carefully, determine who your enemies are. They can do the same to you -- you can't trick any LoC who takes precautions.
"Meet true love" So much for suspense. And, c'mon, LoGs are superhumanly charismatic, healthy, rich as they want to be, etc. and they need Wayfinding as a dating service too? (Though I like the idea of a PC doing this and then meeting their own double. Also, if Masters otGS with superior Psyches can determine what another Wayfinder is searching for Evil GM opportunities abound.)
Is Wayfinding unstoppable? Can other Wayfinders assure that their plots won't be uncovered, that their opponents' security measures fail, etc? If not, everybody's plots against alert LoGs get revealed right quick. Non-noob LoGs would know that plotting is generally unworkable and either go straight to murder, to impromptu "Get 'im, boys!" attacks or just give it up.
