Tirion Fordring's unexpected intervention did not surprise Gedwyn too much, for history is composed of countless coincidences.
However, it is on certain special characters that such coincidences may occur frequently.
Especially for someone like Arthas, who carries the aura of a main character like Long Aotian—if he were easy to kill, he would have been dead a long time ago. There were so many before who tried to take Arthas's head and failed due to various mishaps.
Gedwyn had envisioned similar possibilities, but he never expected that this "coincidence" would be Tirion Fordring, the very man who historically ended up slaying the Lich King Arthas.
One has to admit, the System seems to take a somewhat perverse pleasure in orchestrating the destinies of these characters.
The only thing that truly irked him was Tirion Fordring's premature exit, which meant that the Order of the Silver Hand was one member short, which was somewhat regrettable.
