Malignus appears in Telepath RPG 2 sinisterdesign.net edition.
Malignus offers the Hero a chance to "travel through" time and participate in any of the battles of TRPG2.
"Wait, who are you? The war... is it over yet?"
"When you can See as much as I can, it's hard to keep the time straight! [The spriggat closes one eye and peers at you with the other.] Do you See?"
"The past. The future. It's all present for me to See. Would you like to take a trip through time, child?"
Malignus happened to be the game creator's username on the Old SinisterDesign Forums.
