User blog comment:Lord Loss/Monster Hunter Theory... Blog/@comment-4009941-20140402183150

I think the highlands may have been inhabited before the guild knew about it.

By Pirates and Barbarians.

My evidence for this theory is. Gurens title, Equipment from Gurenzeburu http://monsterhunter.wikia.com/wiki/File:FrontierGen-Pirata_Armor_(Both)_Render_2.png, The classic stry of pirates and others hiding treasures with maps scattered across the land http://cog-members.mhf-g.jp/sp/news/image/6690_1.jpg The maps to find this stuff including the Guren hammer that was supposedly made a long time ago and hidden with maps scattered in different areas such as 2 in the tower, 1 in the desert, 1 in the Volcano and 1 in the Great Forest hidden. Along with various jewels found in the treasure(Used as Cuff decorations for skills in game).

For someone to have made this Guren hammer before guild knew of its existance means someone had to know it existed already. And already faced possibly multiple Gurens before the guild even knew of the region. Also makes me wonder if this is one of the reasons Guren do not tolerate humans in their territory while they remain as guardians to herbivores in the highlands. By the time the guild visits the land they deem it Unexplored, Unknown and inhabited by what they call the Barbarian Wyvern a species that acts as a guardian of the land protecting its natural peaceful inhabitants.
