Wolik

Wolik is the goblin leader of the ramshackle village in the sewers of Dennmarsh.
He will protect the village however he can and just wants to live comfortably in peace with his village in the sewers. He fears the land dwellers who drove his village into the sewers, as they were blamed for everything.
The room where the village was initially located was taken over by a spider. The party killed the spider and told Wolik that it was safe to return. To show his gratitude, he gave Adris his Sword of Courage, which grants advantage on any saving throw made against fear affets.

When you went back in time, you found Wolik living in a cave. He told you how to get out and gave you the boots and springing and striding.
