After trailing the beasts for several days, I think we've finally found their lair. It seems like their den is further in this cave. There may be more of them than we first thought, but after seeing the strange columns and pipes, there may be some sort of ruin here.
My Gran always said those places were full of treasures just waiting for the first person to find them. We've decided to make camp and try to clear out the animals and see if there is anything worth taking.
