Since this is going to be long, I figure I'd include a separate thread for this. Terra Primeva is the Earth 65.7 million years ago, about 200,000 years before the great extinction that wipes out the dinosaurs. I want to treat it just like any other planet, it is accessed through a wormhole, a very big wormhole in fact, one with the mass of 50 Suns, each wormhole end has its own planetary system which includes a moon sized planet (Size 2), a large gas giant, and a G type main sequence star, all of which orbit around the wormhole openings. I'll present the information on those to get them out of the way:
Olympus is the nearside wormhole entrance, this is the entrance that is inserted in the PC's campaign in one of the hexes, and the PCs encounter this mainworld orbiting the wormhole entrance, a G5-V star also orbits further out at such a distance as to put the mainworld and the wormhole entrance within the habitable zone of that orbiting star. The planet Olympus orbits every 4.62 days and is tidally locked with the wormhole entrance, but it is not tidally locked with the star that also orbits the wormhole further out, so a day on planet Olympus, an airless moonlike body, is 5.11 days, because that is how long it takes the planet to catch up to and pass the orbiting star that has an orbital period of 42.9 days. There is also an large gas giant with no moons orbiting at 0.5 AU once every 18.25 days, this gas giant alternates between hot and cold depending on its position in its orbit relative to the orbiting Sun, when closest to the star, it almost gets as much sunlight as Mercury, As you might suspect this gas giant has a turbulant atmosphere.

Asgard is on the farside of the wormhole, this is the side that is 65.7 million years in the past, its system set up is fairly similar to the nearside planetary system, but with a G7 V star rbiting at 0.8 Au once every 36.6 days. As Asgard is also tidally locked with the wormhole, it has a day lasting 5.19 days from sunrise to sunrise, and another large gas giant. The denizens of both planets are robots. The robots do not know who put them there, beyond a certain point in the past, their memory and records have been erased, they are as intelligent as any human, and have a religion based upon what they call "The One True God," their population is carefully balanced ad is quite stable where a new robots is manufactured to replace the ones that are no longer functional and cannot be fixed.

These robots are good with languages, after hearing the PCs talk for an hour or so, they can pick up the gist of their language and in two hours they speak it as if they were born knowing it. They are polite to off-worlders, but not particularly curious. When asked they don't know who built the wormhole, all they know is it existed as far back as their records go. The robots by the way don't travel through space, that is why their starports are so sparse, they don't use them, instead they download their software through the wormhole into another robot body on the planet on the other side.
This symbol also adorns the main building of their unused starport
The Wormhole leads to another part of the Galaxy. If the PCs travel through it in their starship, after making a successful astrogation check, they realize they are in the past, examining neigboring galaxies through their telescope determined it to be about 67 to 65 million years in the past at the farside of the wormhole. The farside end of the wormhole is isolated within a rift, there is one other star system within range of a Jump-6, and that is a G2 V class star 1 parsec away, there is literally nothing else within range, the next nearest star system is 20 parsecs away. the G2 V class star is a single star with 8 planets, four rocky terrestrial planets and 4 gas giants, the two inner ones are large the two outer ones are small. This is in Hex 0201 of the Farside Subsector. There are only two systems in this subsector the Wormhole and the other star system 1 parsec away.
Here is Terra primeva, one of two star systems that can be accesses in the Farside subsector. The Earth at this particular time is within a Galactic Rift, from which only the wormhole system can be reached and no other star systems are reachable from either system, not even with a Jump-6 drive, so basically it is a way to get to this planet so we can have some dinosaur fun. The Earth at this time has some unusually large creature, which I intend to present here in this thread

As you might expect, this planet is inhabited by dinosaurs, the inhabitants of Asgard and Olympus never visited it, as they don't have starships, and as there is no reciever to accept their software, they can't get here unless the PCs offer one of them a ride in their own starship. Upon closer study of the planet, they determine they are 65.7 million years in the past. The PCs can't go anywhere from the wormhole from here, the planet at this time just happens to be traveling through a galactic rift, though the night sky has plenty of stars in it and the Milky Way band is clearly visible on a moonless night, the stars other than the marker star for the wormhole are all more than 20 parsecs away. So count this as one planet, not a whole new subsector, despite the wormhole that brings the PCs here.
