Just posting this here in case anyone hasn't seen it, this is currently the plan for the Fire Giant mission: 

So here’s what we’ve got: 
1) Holmshire investigates the wreckage of the high school and discovers not an ordinary fire. Perhaps he can be burned by a still alight flame and realises the fire isn’t mundane but divine in origin. 
2) Jorick investigates the case, evidence from locals, the demigods at the church and the bishop in charge of the school and begins to suspect there is more than meets the eye with the bishop due to his ability to lie detect.
3) We pool our knowledge together and we decide we need to investigate the Bishop further and suspect he is somehow involved with a Fire Giant, the most logical cause of 
divine fire. 
4) I (k-97) decide to test the Bishop’s doctrines to find any inconsistencies due to being a former catholic priest. Upon finding reasonable cause for suspicion I force him to tell me everything about his involvement with fire giants and he spills the beans confirming our suspicions. He however is now aware that demigods are involved and quickly leaves my presence to warn his master. I don’t initially make this connection until I return to the others and they point out our problem.
5) Realising we need to do something, Sneaky Demigod NPC tracks the Bishop and tells us where all the children are through a phone but is quickly killed by the Fire Giant’s minions before he/she can return as they hear him talking on the phone. 
6) Imagination drives us everywhere and deals with getting all the children out while the fight is going down. Holmshire and RedDusk fight the Fire Giant alongside three Fighting Based NPC Demigods who all die. (You'll be fighting thralls too I imagine.)

Bea, you are the only one who hasn't come up with their contribution to this mission so what do you think you could do?

The other thing we need to do is deal with the character sheets of the NPCs, it doesn't have to be detailed but enough so we know more or less what the living demigods would know of their characters (Name, Race, Sex, Appearance, Heroic Role and Divine Parent). Might be worth adding a Personality since we don't have a history and these characters won't be played out for long in IC (so we can't ascertain personality from roleplaying).
