This mod is fairly simply.

1: It makes cave dragons adults at 5 years old, allowing them to be tamed.
2: It reduces the age at which cave dragons and regular dragons reach full size.

This upload includes two versions: "Dragon Tweaks" is the more balanced one, dragons will reach maximum size in 300 years.
"Dragon Tweaks Extreme" makes dragons take only 10 years to reach maximum size.

Hope you guys enjoy!
