My bad, I didn't see. That said, Lecch is a former Grandmaster, one that specialises in the knowing of things which would imply that his sensory powers would be second to none (as is represented by his mastery of drain knowledge, the various senses, and his ability to close his mind to other's probes). Force stealth can only hide one so much, it's not a guaranteed hiding place as much as an increased chance of success - which is completely counteracted by Lecch's sensory abilities.
Unless of course you disagree, in which case I'll edit accordingly. Lecch would simply spend a post finding said character through the force instead of combining the locating with the moving to rendezvous. As this isn't PVP, I'd suggest just leaving it as is. What does it matter? I get that the you want him to be all enigmatic and mysterious, but that approach doesn't really fly when you're faced with someone like Lecch - he'll treat it with suspicion. It's your choice, I don't really mind.
