Yorel Anbidian in Swanton Keep is in a bit of a bind. A wizard has ordered a magical pair of gloves, but Yorel is out of the special skin he makes them from, and his supplier is missing. Unfortunately, he doesn't even know what creature the skin is from, so he sends you to Mathien in Snowdonia Station with a small scrap of skin for him to identify.
Mathien identifies it as the skin from a frog named Worry Wart which can be found at loc 31,34 in NF. The skin is delicate, and you need a complete skin, so you may need to kill him more than once.
When you return a complete skin to Yorel he is so grateful that he makes a pair of leather gloves for you as well.
