Question: Do you keep it?
Response: Yes. He was trying to get rid of them, and I want rocks.
There are way more pebbles than you need for your experiments - and really, if they were just for experimenting you wouldn't be keeping them. But you want them, and Allan looked so glad to get rid of them, so you're doing him a favour, really.
Maybe they'll make some nice decor around the front yard, too, and you can ask the neighbours about setting something up for them.
On the way to the garden, you mentally turn over the puzzle of breaking the sigils once they're installed - definitely ruling out only a couple of differently coloured rocks, because who wouldn't want to pick out the single differently coloured rock (many people, maybe) but you also would like to use some colour because you don't like the idea of trying to break the sigil without being able to use visual cues.
The solution that makes the most sense to you is to make at least the outer circle out of similarly coloured pebbles, and hoping they don't prove to be alluring enough to pick out.
You reach the community garden and relay your thoughts to Stan. He agrees that a separate colour for the outer circle will be the way to go.
'I'll organise a time to overhaul the paths.'
'Oh - I'm sure we don't need a full overhaul -'
He waves your protests away. 'We're in need of a renovation. This is a perfect excuse. You working with any deadlines?'
You give him about two weeks before the witch meet, just to stay on the safe side.
'We'll reach out when we need you,' he says.
A few days later Dessa's reply comes in the mail. You crack open the seal and read through it without bothering to come inside first. She's written about the hot winds Deema described, complete with calculations and sketches of air moving through different points in the Great Dividing Range (they're fascinating but she's much, much smarter than you - maybe Deema would appreciate them).
I'm sure you know why I can't give you an exact date on the hot winds, but if you're keen, come by when the season starts in early autumn.
You consider the options - gambling on the possibility of a heatwave in the south west, interfering with whatever the wizard has going on in the south east, and a predictable phenomenon with a local guide (who you'd have to sneak around, unless she's cool).
The choice seems obvious, and can be done after the meet.
You come inside and show Deema the letter.
'That looks like what we're after?'
'In early autumn,' you say.
'It all feels so painfully real,' you murmur as you take the letter back.
What do you do now?
Write to Dessa to take the offer up.
