FYI: Dig had previously opened the wards to all members of the Order so they could apparate right in and out of the house, in case of medical emergencies.
Since Veronica is there now and he isn't one to underestimate Bellatrix (he grew up with that crowd, he knows how they work), the wards have been strengthened. No one can apparate in or out of the house, or on or off of the grounds. So people will have to start apparating to the gate (of the stone wall) and walking in. The new, tough wards are... vaguely dark inspired in that there's probably like, a moment where you can't breathe when you step through the gate and the wards figure out if you're allowed to be there or not.
Just so's you know. In case anyone might comment on what a pain in the ass walking in from the gate is (it's a big property, so it's probably at least a 2 minute walk and you can't see the house from the gate due to wall/trees), or how the new wards are kinda scary, or even, say, how the girl must be pretty if she's worth going to such lengths. *grin*
