Whenever I start a new Early Era campaign, I notice that a good number of settlements will have the ability to recruit a unit that doesn't seem like it belongs there. The examples that I best remember are Lustinian Javelinmen in Caen and Viking Raiders in Metz. I've heard of the British being allies with the Portugese but that was during the Napoleonic times. I doubt some Portugese javelinmen suddenly decided that Normandy was their homeland and moved there. The Vikings sound more reasonable but I still have my doubts.
I checked that apparently you need the hidden resources of portugal/denmark/norway to get these units and the descr_regions for Early Era doesn't have these hidden resources listed in Caen/Metz.
Is the campaign supposed to be like this?
(I must admit that I like getting good quality javelinmen as england so early. French and German knights are a lot easier to deal with when you have portugese javelins hurled under an English banner.)
