Riddick/Vaako Fanfic

[Guest HaniOwl]

Hello,

I’m attempting to find a fanfic where Riddick and Vaako get left on Not-Furya. There is a part where Vaako gets injured and Riddick hides him under this boulder or that’s where they sleep for protection, I don’t quite remember. There is also another scene where Riddick continuously gives himself small portion of the venom from the creatures in order to build up an immunity to it, he tested on the dog/puppy before himself. After a while they find the building/settlement, and set off the alarm in order to inform the bounty hunters their location and slowly pick them off. 
 

Any help would be greatly appreciated!
