I know this is may not be the type of discission Im ment to post but i have no other alternative, I need help to finish this map, im think im close to the end but ive hit a wall and am cluless as to how to proceed.

Im at the core and need four prison keys which im told are beneth the core and somthing about needing the green planet with an ornate key.there is also the first of the seven golden relic thing but im unsure if that is related to completion.so if any one has beaten it i would really appriciate the help. Thanks

p.s map is awsome adding more incentive for me to finish it.
