Glowing firefly

Glowing fireflies are found in the night time near Solhaven in the plains there along the trail to Wehnimer's Landing.

In order to get fireflies, you need to go to the Solhaven pet shop and purchase 4 glass tubes for fireflies, go outside at night and WAVE the tube around a bit until you catch one. Fill all 4 tubes and make sure this is the LAST thing you need because the fireflies can die and the tubes cost 30,000 silvers each.

On the plus side, the tubes ARE reusable.
