Here are the six power-brokers for our northern war:
Richard Ferrier, Lord Hadley - this fellow is our initial protagonist. A pro-Yorkist 'new man', he shall be seeking to put down all resistance in the area on behalf of King Edward IV. He even sports his Blue & Murrey colours as his livery, to advertise his loyalty to the new regime. His own symbol is a castle tower, which shall hopefully grace more than a few battlefield triumphs. He is described (i.e. rolled up as described previously) as easy-going and liked, but unscrupulous. Decently skilled at warfare, his main characteristics on-field are his experience and - above all else - his driven personality, relentlessly pursuing whatever he perceives as necessary. Pity any servant that fails to produce the goods for the big man...
Thomas Fawcett, Lord Wolviston. Another Yorkist man, sporting blue & white livery plus a natty 'cross' heraldic symbol, poor Lord Wolviston is a bit too dour to be popular. Genuine in his morals and dependable as an ally, he is nonetheless a grim figure and something of a 'plodder'. Still, he's powerful and a decent fighter, so who knows if he shall become the favoured of the crown?
John Demain, Lord Potterchester. This fellow is a pro-Lancastrian loyalist, giving only notional - if that - loyalty to Edward IV, while his longing for a restoration for Henry VI is an open secret. His livery is red and yellow, and an ermine symbol is used by his men. Although of slippery loyalty to those he feels are expendable, there's no denying his formidable reputation: popular and generous with the local gentry and commons, he's well-liked and also said to be a born fighter - deadly on a battlefield, even if lacking experience (no doubt something he'll soon put right.)
William Johnson, Lord Turstoke. Sporting red and black livery and a Boar symbol, he is also a Lancastrian die-hard. Far less well thought of than Potterchester, Lord Turstoke is widely experienced in wars but sadly this has given him nothing but excessive chances to prove his ineptitude and laziness. He is said to be very charismatic and likeable in person, so clearly he's a decent enough sort - just not cut out for warfare. More of a lover than a fighter, it seems!
Lionel Perkins, Lord Monkton. Blue and Yellow livery, with a crossed-keys symbol. He's a Yorkist, and the younger brother of the Lord Whitcaster (of whom more below!) He may be a bit sluggish in action and something of a dull, bookish thinker - but when he moves, he moves! Both skilled and experienced in arms, he is a dangerous fighter on the battlefield (when he eventually decides to get there...)
Richard Perkins, Lord Whitcaster. With his leaf symbol and red livery, Whitcaster is a faithful Lancastrian. His conscience has kept him true to the exiled king, even as his younger brother the Lord Monkton has treacherously aligned himself with the Yorkists and split the family apart. Decent and experienced, he is a solid and capable opponent.
(When generating random names, I never noticed that two of the powerful lords had the same surname. The chance for the two nobles, close by on the map and split between the two factions, for not being close relatives split by the wars was too good a dramatic fluke to pass up!)
