Welcome to Paperdemon, Degare! The Paperdemon ARPG currently has challenges. Our webmistress, Bogusred is adding to the ARPG bit by bit new features. Currently right now we have a collabration challenge, the New Years Crossover challenge with Dracostryx and Dragons of Aquella.

If you're interested, you'll need to make yourself a character, pick an element, and register the character, then we have cycling challenges! Our last one was a Hallowen based one, then a Christmas exchange :) 

I hope this answers your question ^^
