Jake didn't even have to do anything to get his answer. Besides the corpses and the tunnel entrance, there was only one thing out of place in this goblin camp:
The sapling.
This young tree was not very tall, about his height, and its trunk was not wider than his own neck, which all things considered was not actually that narrow. The bark was still a little green, but dull and crumbly as if the sapling was dying. Its wilted auburn leaves supported this statement.
If he had any doubt, several amber sap seeped out slowly from several gaps dotting the trunk and Jake finally found out where the sweet scent was coming from.
A quick scan told him the rest.
