For the most part due to the few ways to get new skills I would like to work the existing skills into A). One new Skill or B). Underneath existing Skills

Law, Administration, Siegecraft, Leadership, Strategy - I propose these all fall underneath the new skill Rulership

Rulership (Intelligence)
You are versed in the many aspects of ruling a realm from the adminstration to warfare tatics.

>Administration - DC 10 for every 5 points above the DC reduce the maintence cost for holdings in your realm by 1GB, use of this skill cannot reduce the cost below 1GB

>Law - Not sure really, maybe just allow it to be used for a skill challenge in the event of Matters of Jusitice.

>Leadership - DC 20 (can't take a 20 but can take 10) check 1/domain turn to improve the morale of 1 province per level by 1.

>Strategy - DC 15 usual benifits

>Siegecraft - DC 15+Castle Rating Usual benfits.

I wouldn't mind making it a variable attribute skill just not sure if its adivisable to do so.

Diplomacy - Falls under current Diplomacy

Intrigue - Falls under neath Either bluff or Thievery (I lean to bluff)
