Did the first session of in the New world. (Party is lvl 5, this is a continuation of another campaign) Spent a little time in the old world wrapping things up, letting them decide which ship to get on, so they could meet some of the NPC's on the trip and find out about them.
Upon arrival they were asked to scout the beech before bringing in everyone, so they took a small group of soldiers and went in closer. They found a hunting party of lizardmen fishing and cooking a kill of some large animal (dinosaur like). Having two dragonborn among them they decided to see if they could parlay. Ended up being invited to share a meal. They then scouted the nearby forest and found gnoll tracks. The lizardmen explained that the gnolls sometimes try to steal their kills rather than take down their own and were probably waiting until night fall to sneak or attack them. The PC's offered to camp on the beech that evening and trade stories. The soldiers went back to the fleet to report. That night the gnolls attacked, the lizard men and the pc's took down the gnoll raiding party pretty easily with their combined forces. The next morning the lizards departed with their fish/meat to return to the swamp.
The PC's did another scouting session to insure nothing else nasty was nearby and that they got all the gnolls. (Some got away). The soldiers brought in the first load of supplies to build a small fortification for unloading and providing emergency protection. The lumber jack took a group to the forest to start finding more suitable lumber for building. The fleet scouted the coast line and found the grippli island and the river mouth, and decided to send a scouting party to the river to evaluate if they should build there or not. The players decided to head into the forest and make sure the lumber jacks didn't get killed. Found a group of Lemurian skeletons, and killed them. After that they decided they should seek out the "other" tribe the lizards told them about and see about making an alliance, as anything using undead as minions must be evil.
End session 1.
Next session: traveling to look for the gray tooth or tracking down their buried treasure (they have a map they acquired in the old world, ala a pirate map, written it up as sort of a skill challenge but not really.). Have several 5-6th lvl encounters depending where they go (a young trex, velociraptors, a giant snake, a young brown dragon, a demon, undead, grippli, gray tooths and black ravens). While they are out the colony will clear the area around the site and build some walls, maybe a main long building for temporary shelter from storms.
