So, I've been thinking - what if you've met a guy in the game and started doing things together, but don't want to share your personal details like e-mail, but still want to stay in touch - preferably, using in-game tools, because I like my games self-sufficient. There's two ideas that I'll post over two threads, like I'm supposed to. The other thread is here.
The first one is pretty simple and really doesn't add any new mechanics, just recombine existing ones. Basically, it's a construction that allows anyone to send you a Jabber message, using the same system as trespassing notifications, from the game, without having to leave a scent. Or simply letting you know your attention is wanted if you're away.
I'm using mundane descriptions, but these things are clearly magical - after all, only the hearthling they're tied to hears them, and this "sound" carries far beyond what sound usually does. Putting a dream into all of them kind of, sort of means that.
It's actually a few constructions for you to choose from. The difference is how far you have to be to hear it. Otherwise, they work the same: they're tied to a specific hearthling, and when anyone uses them, if the hearthling they're calling to is within range, they get an in-game message "[name] is calling for you" if online, or the same message via Jabber if offline. Naturally, they have to be subscribed to Jabber for that. A nice addition would be customisable (By the owner) messages.
The actual range depends on the quality, but they all stay within their scale.
Knocking board: quite simple. It's a board you (Wait for it!) knock on! Built from a block of wood and "A beautiful dream!". The range scale is a couple screens - just enough to cover your claim.
Small bell: wooden block, string, a couple nuggets of metal and two dreams. Scale is several local maps, but less than a full region.
Outright magical thingamabob: whatever, but rare and expensive - I can't really name any mythological calling devices. Range should be up to a supergrid.
They're easily exploitable. To avoid that, every time a hearthling uses one, it takes some time to "recharge" - around a half-hour at least. Or something.
Yeah. The idea's rather raw. Kind of expecting someone to add to it.
