Now, I know you don't get a nickname like "Beast Queen" without being one tough lady, but when I saw that giant ape, I still thought we were buggered. Fortunately, Mei-Yin's got more intestinal fortitude than yours truly, and somehow, someway she was able to pull out a win. Glad I'm on her good side!.
I already found the second key, but I want to take a look around here before we head back through the portal. This ape either lived here, or was released when we activated the obelisk. Finding out how it survived in this isolated environment or how it got here could prove useful.
