Where The Hovel Came From:
The hovel was originally non-existent in the past of Tremulous' aliens. Eventually grangers had to find refuge from other relatives of their kind, getting beaten down and assaulted by their own kind. An elite group of grangers formed to find a way to stop such a massacre of innocent grangers. The original plan of the hovel failed miserably, resulting in a tube filled with acid that killed grangers, instead of storing them. Sadly, the granger who thought up the design was eaten by a tyrant.
The elite grangers grouped up again, and finally made a breakthrough. They would create an object they could jump in, as if a bush, but be safe from enemies and yes, their own blood. Reluctantly the test-granger, paid one evo to do this, leaped off of a high place on a map humans call Ka-rith. The granger plummeted down, purring all the way as it sped toward this newly structured building, it then realized a flaw in the making of the object. It wasn't like a bush, it was like long pointy spears. The spears impaled the grangers' body and the granger made one final, long purr as it's light-filled eyes glazed over.
The elites were close to giving up, two of their members had died in vain. Possibility to find refuge looked impossible. Many granger families hopes were crushed, just as the plummeting granger did. Hope was lost, many grangers just accepted the life of abuse and sodomity. Even some of the elite and wise grangers began accommodating to the lifestyle.
There was one granger who still had hope, he wasn't good at designing buildings of great importance like the elites, nor did he have the intelligence to tell a goon from a camel, but he had ingenuity and a will to change the granger community. It worked many hours, every day, evo-less and starving, it came upon the most shocking realization in history. Although it's design looked more like some of those magazines those humans look at while camping, and eating smores, it was suitable for a big object to fit in. Granger went to tell the news to the great ones, skipping along purring with anticipation.
Sorry I had to end it there, even if it sucked, I love building suspense.
My point is? The hovel is a PART of tremulous, no matter what. It will still be here even if tremulous lasts 100 years.
