I don't know if you can have too many threats, really. I just did the first session for my new campaign last night, and I ended up with the following;

The Immediate Area
•The Waterbearer's Source, a furnace
•The people who populate the source, a family
•The Show's bike
•The Angel's assistant, a pain addict
•The Hocus's scene, sybarites
•The local drug problem, a disease

Nearby to the North
•The North Pass, a maze

Farther to the North
•Odin, a rival hardholder who demands the Source
•Asgard, Odin's fortress
•The Einherjar, Odin's army, a hunting pack

The Source, family, bike, pain addict, and scene came out of character creation. The drug problems arose due to the scene missing his Fortunes roll and being judged. He decided it was because he wasn't sharing his drugs, and the scene then went and failed to kick in the Angel's infirmiry. The child-thing wanted to run some messages, and said he'd worked for this King named Odin before. Some Chinese whispers between the Water heater, Child-thing, and Odin resulted in Odin attacking, getting held back, then embargoed.

The drug problems, pain addict, and the landscapes to the north didn't come into play, as no one went north and Odin's demands kept everyone busy.
