1 - The missing villagers of Tar

Just as a side note for those who don't see that well in darkness, there are burning trees east and south of your camp that shed bright light on their surroundings (40" bright + 40" dim)

Even a giant spider can't break free from the grasp you powerful companion has on it, and you are in position to do whatever you want to it.

Trees continue to burn with lots of smoke, but the cracks from their agonizing branches is the only noise that can be heard (if you killed the giant spider, otherwise its shrieking will continue for some time).

What do you do: will you go back to sleep? With or without extinguishing the fire? Search where your attackers were coming from?

Warning: you captured a giant spider, not one of the strange kobold-like thing.
The creature seem to react to some word that make you that that it has been tamed and trained to combat but isn't particular clever. It's about as smart as a dog, with more wild instincts and lots more eyes and legs.

After an initial fearful reaction, the spider calms down and take the offered food. It kinda squeals, trying to express the discomfort of its situation, before you untie it (unless someone stops you from doing that).
As you are done casting the spell, the giant spider -an impressive beast!- seems keen to stay around you and probably obey basic order. It approach and pushes your bag with its head, looking for more food.
