Eratosthenes must die!
 

How as a GM do you prevent Eratosthenes from teaming up with a gate jumping Hipparchus to determine the latitude and longitude of every spot on Cidri?

Mr. Cthulhu, this is your non-Euclidean wake up call.

Maybe there's more than one sun, but only one is visible at a time from any particular spot on the planet.

Well:

1) I have a map of my campaign's part of Cidri, and I know where the gates connect to.

2) There is no one network that even connects all of my campaign.

3) There are usually no known commercial gates out of my campaign.

4) Eratosthenes and Hipparchus and the Scholar's Guild do not even have a complete accurate map of my campaign world.

5) Eratosthenes and Hipparchus and the Scholar's Guild also do not have particularly extensive knowledge of the extent of a very high fraction of the gate networks that do exist.

6) The gate networks that do exist and that get frequently used, tend to break down and add other links from time to time.

7) Cidri is so enormous and/or flat that trying to take lat/long readings may be difficult.

8) I think Cidri involves multiple worlds.

9) Cidri seems to involve a suspicious number of places called The Land Beyond The Mountains, and even more places claiming to be Southern Elyntia... now a bunch are becoming known that are geographically similar but of a different size.

10) Cidri may also involve other sorts of planet than round rotating planets in space.

11) Cidri actually seems to be more like a multiverse.

That's the way I'm choosing to interpret it. I like Worldbuilding, so I'll make up my own map's worth of stuff — specifically, a group of largish islands — and just treat it like it's all sitting in a kind of pan-dimensional crossroads, like the Bermuda Triangle. Sail this way, and you'll come to Southern Elyntia; sail that way, and it'll be Atlantis. Or Feudal Japan. Or the Edge of the World. Or Wherever.

Kill them. Simple

Reverse ringworld with sequential suns rotating around it. Black hole in center to provide gravity

Don't kill Eratosthenes! How will we sieve out our prime numbers?? :)

Re: Eratosthenes must die!
 

Cidri is clearly a sub-prime world.

Ask Sundaram. If They got to him, too, then there's Atkin. I won't name any more here in case They're monitoring our communications.

But it has to qualify for the jumbo mortgages.
