Greg speculated that to become a Hero, one needed to:
1. Participate in at least two “great events” – heroquests outside of those known by cult or tradition. This would include cult heroquests that go outside of known paths.
2. Have at least four special items or abilties
3. Have at least one unique item or ability
4. a final test against one’s own god where the Hero proves their independence.
I’m inclined to think that these more or less define our Gloranthan Heroes, although of course there going to be exceptions. But Jar-eel, Harrek, Argrath, Jaldon, Gunda, Beat-Pot, Ethilrist, etc., all fit into this system nicely.
Note the importance of the Hero being independent from one’s god. Even those heroes who are revered as avatars of their god – e.g.,Harmast, Alakoring, Argrath, Hon-eel, Jar-eel, etc., proved their independence to their deity!
