Exploration!
Some people might think that the smart thing would be to leave, but Gregor knew that was nonsense. The most dangerous thing in the world was a closed door, if you didn’t know what was on the other side. When it was bad, you always found out at the worst possible time. And if it wasn’t bad, why not open it? Besides, the door wasn’t even locked! Well, not really. Ten seconds with a lockpick had it yawning open, and not into a stygian darkness. There were the unmistakable faint glow of lightstones on the other side.
Gregor almost whistled. Elf-iron and lightstones weren’t cheap these days. There was probably all sorts of portable loot lying around, including the lightstones themselves if they were small enough.
The lights were dim, but shone brightly enough to reveal a large square room, with two doorless rooms to his left, and two with doors on his right, plus an altar set into a recess opposite him. Gregor froze when he saw the altar, watching it like a bird watches a snake, and for the same reason. After a minute, he relaxed. No miasma, no ghostskulls, not even a purple-black glow, he thought. It’s probably safe.
Gregor very clearly has finely honed survival instincts that are very different from what our own would be.
He’d get killed crossing one of our major intersections, so yeah. 🙂
