The Nightmare’s hold on Kenny has become so intense that the sacred fire that gave him to life is on the verge of going out. As a result, Kenny has had no choice but to flee the town in an attempt to stay alive and regain his strength. As for Rhed, she’s amassed so much treasure during her adventures with the Piranas that she'll never want for anything again. Instead, a much-deserved retirement awaits her...
From Monday, September 17th 2012, Kenny and Rhed will no longer be available in the shop’s packs. However, players who already own them can continue to use them as normal. Sales of the two characters on the Market will be blocked until the morning of Wednesday, September 12th.
