Open Grave

Open Grave breaks out into:

Alternate powers
Diseases
Encounters
NPCs
Rituals
Story
NPC Templates
Traps
Reference
and probably some magic items

There are also:
Artifacts (I can't do anything with these really)
Skill Challenges

Skill challenges is something new that started appearing in dungeon. They are little stat blocks that detail how to run the challenge. I don't have anything that parses them, but my guess is they'll be something like the Vehicles. They'll also need display classes built.

I've finished:
Alternate powers
Diseases
Encounters
NPCs
Rituals
NPC Templates
Traps

I'm still working on:
Story
Reference
and probably some magic items
