That sounds interesting, a war of attrition would certainly be a good tactic against Higan. In a short paced high intensity firefight he'd come out on top, but a long battle would wear down his incredibly finite ammunition. 

Alrighty, you can set the scene if you wish and also because it makes sense, considering your character's habits Higan would be going to it. If you keep its location in a wider geographical sense vague that would be excellent, as it fits into Higan's personal story. He's hunting down anomalies that have entered the world of the Ramor and killing/capturing them. If you plan to make serious adjustments on Shashe let me know so I'm aware I'm fighting roughly the same character.
