As long as the core is molten, it will have some dynamo effect. And as Umbran says, the star is less dangerous. Another thought for a geological cycle would be the tides caused by the moon. Since I want solar and lunar eclipses, the moon is going to have to be bigger or closer. Too big or too close, though, seems like it would create a dual planet situation, rather than a planet and a moon, so I might have to go for partial eclipses (which would mean there is absolutely no darkness on the day-side). Either way, with a slow lunar rotation, the tides will move slower. A larger or closer moon will create more drastic tides, which will likely drive the lifecycles of aquatic life. Tidal shores will be big. If life started in these tidal shores, they could be the basis for a large food chain. I'm not sure what I want to do about sleep cycles. Sleepless humanoids as the norm feels odd, and I wouldn't want any race to have such a widely different sleep cycle than the others as that would affect play. Aside from the geology and astronomy of the world, I started putting some thought into the cultures of humanoids living here (as every gaming setting has some sort of multiple races). I think the night-siders, or at least those far enough into the twilight to see the stars, will be the more advanced, both religiously and technologically. They have the stars to watch, which leads me to believe they will have a deeper knowledge of mathematics. They will likely worship the omnipotent stars, and will most definitely have noticed the paths of the outer planets in their system. They will be able to keep time. The day-siders seem like they'd be more primitive. I haven't given them too much thought yet, but I wanted to find a way to avoid the immediate thought of having the daysiders be good and the nightsiders be evil. I also think that mountains in mid latitudes (pretending the terminator line is the equator, since it will be more apparent than the actual equator) will house the largest day-side cities in their shadows. The mountains will collect rain, and as long as the mountains are small enough, some of that rain water could flow to the shadow-side; especially if the people create canals to channel the water around the mountain. I wasn't looking for the moon to create a "day and night" in a duration, just to give the day-siders something to keep time. I'm thinking to have the day-siders keep time by months, counting each time the moon rises.</blockquote>
