A giant tree which has somehow managed to grow up in the literal MIDDLE of a crossroads. There is an exit from a goblin settlement under the tree.

The tree, judging by size, is very old; easily older than the oldest human. Judging by the surroundings, however, the tree is a recent addition to the roads.

Map of the tree and immediate surroundings

This tree covers the hidden entrance to Goblin Undertree.

There is a band of elves that seem to guard the area around this tree. They aren’t happy with you, because you killed the son of the largest source of income they had.
