I've been a fan of Hochland ever since 4th Ed., although my reason for choosing the province was initially rather superficial - my favourite colour is green, and I didn't like Stirland's 'yokel' fluff, so that essentially left me with Hochland
Brief army background: My army (known as the 'Forlorn Hope') was originally composed of veterans of the SoC, but since that has been retconned by GW, I'm in the process of creating new fluff that will explain the army's rather grim name and disposition, as well the the presence of large numbers of foreign mercenaries and worshipers of Morr, Myrmidia and Sigmar. The army itself is commanded by Elector Count Aldebrand Ludenhoff's youngest brother, Theodore Ludenhoff (with few estates to inherit, he was sent off to make his name in the military). Hopefully when I have some more time, and a spark of inspiration, I'll post some detailed fluff in the background forums.
