Will Dee is a player spoof who was found in the Combat Academy. The Wilderness, also known as the wildy, is what his name is referring to. He is wearing full Statius armour, Steadfast boots, Barrows gloves, and a Divine Spirit Shield.
When asked about the people on the benches next to him, he would tell the player about Virtus, leather and dragon armour, and how they can be obtained. He could also be asked about his own armour, and would tell the player about the Wilderness.
