Magmeld Emissary Leader Lada:
Thank you! Thank you! Please, you must go to the cave entrance behind Anghel Waterfall and find the Wisp's Favorite Large Verdant Wilds . Use the Glimmer Crystal that I just gave you, and Wisps will swarm in. Take THEM to Slaski in the Ancient City of Arcan, and he'll be much more likely to talk to you.
Cats are cautious by nature, so you won't get anything if you go in empty handed.
