First thing comes first.

-Make a copy of whole game folder.(To avoid updates overwrite your changes. Read-only won't do.)
-Backup whole script folder.

Now we're safe.

Now that Crime is finally a selectable faction, and to make it active is..

1.Crime won't attack anyone.
- In script/official/power.dat, search for 'power crime'. Remove 'fix = home'.

2.Not a single faction attacks Crime. What the-

resetTruce(lion,crime)
resetTruce(makan,crime)

resetTruce(alcatraz,crime)
resetTruce(fevnir,crime)
resetTruce(reinald,crime)
resetTruce(alfheim,crime)

Ace Factions Tips

Final lasting powers.(Make their factions last long and prosper)
- In script/official/power.dat, look at 'diplo ='. Add '__*100' to each faction you want them to last.
ex.
reinald, diplo=alfheim*100,fevnir*100
alfheim, diplo=reinald*100,fevnir*100
fevnir, diplo=alfheim*100,reinald*100
(Result is Reinald, Alfheim and Fevnir will likely to be last 3 major powers fighting each other)
#How it works: Ace factions likely to ally with each other to fight other major power, and eventually fight each other when no other major power left.

Might as well, add common enemy.(Make them consider each other as ally)
- In script/official/power.dat, ex. diplo=crime*0.
- In script/official/unit.dat, ex. enemy=demokrishia

Empower the leaders.(Make them more like protagonists)
- In script/official/unit.dat, search for those leaders and change their stats.
(This is the fun part. You can even make Agnes move at high speed and firestorm enemy to dead)

Called 'Ace' for reasons.(Make them desirable factions to join)
- Do accepting races in previous section.(Also should you need to do it in unit.dat for each leaders)
- Re-adjust races negotiability.
(To make your ace factions be able to recruit heavenly characters to join their side)

Don't forget money, it's in power.dat.

Comment and pray for your savior.
