Rolls made:
1. Cavern complex with primordial beasts
2. A single natural cave—the Cave of Fate
3. Underground seaNot all of Maar's creations would live through the whole Age. Some of them fought, and those made of weaker elements were no more. Others, of flesh, grew decrepit and unable to compete with evolved critters under the sun, retreating into the cold underground to hibernate. Yet more beasts of exotic origin were simply... forgotten. In the future Ages, they may yet resurface.
Maar himself withdrew from the world, but he left an all-seeing eye deep underground, through which he would be alerted when it was time to gaze upon this world again. The cavern around the Eye, aptly named the Cave of Fate, became a sanctuary of secrets no mortal mind could comprehend.
The lifeforms churning in the ocean had already given rise to first megafauna, when the Eye registered fungal life down in the underground sea as well—fed by chemical energy of local volcanic vents. From there on the development was rapid. In only a short epoch three species in different parts of the world had developed enough to classify as sapient, and all three were projected to develop culture.
Choose one:Dwarves. A bountiful vein of native gold forms in the thick of earth, and the brown-furred rock-apes evolve into dwarves.
Goblins. A guardian wyrm watches over mithral ore as a handful of tailless mountain-devils become what we'll know as goblins.
Amphibians. A river finds its way through the underground, washing open gem caverns and giving rise to an aquatic civilization.
Infernals. There is a disturbance, and outworld beings contaminate Maar's creation with their arrival. Also, magma.
Do note that other civilizations will still appear, you only get to determine who gets a headstart and the extra map features.
The primordial beasts will also receive names in that culture's language The beasts will receive names in the language of the culture that encounters them first.
