Summarization works for me: it's a bit vague as to how Webs are created (Anne Bishop seems to leave that to the reader's imagination), but it seems to involve using the Jewel to create the psychic threads to weave into the Web) and I imagine they reinforce the webs about once a month, perhaps at the new moon (somehow I see the darkness of that point in the moon cycle as especially bracing for Saetan, or it could just be a convenient time to remember, like changing the batteries on your smoke and carbon monoxide detectors when Daylight Savings begins or ends).
