Yeah Nivm, that's the connection. Btw, not sure if you have seen it but i have made quite a few answers on the wave, including the chapel. And among things i have written there, it all makes most sense after looking at the mesh (involves eighter our sftp access or e-mailing (my e-mail is the one i have on wave btw))
If comes about Klyros not landing near the chapel. If comes about silence and some respect to the place, I'd say it's a matter of unwritten rules. Also if comes about gliding down to land on the chapel - it's pointless, it's has quite a sharp roofing and there are no entraces too.
If comes about silence, well I suppose deep in the chapel, the street noise is somewhat lowered, but it is important to notice that it lies on a fork of 2 main streets. The one seen on the screenshot is leading to the Landing platforms slums area (but it is also the shortest path to the landing platforms itself from the Blackhole quarry) It's again seen better by looking at the 3d stuff.
Again, no Klyros will attempt to land on the chapel and Klyros gliding down from building exit towers in the neighbourhood will be trying to land on the streets (attempting to not crash on someone else head too I'd imagine ;o)
The roof texture is done and IMO it looks eighter as ceramic or some metal
