Towards the end of the temple, you'll enter an Astrisk shaped room with protrusions guarded by statues with burning lasers. On the map their will be a small room behind one of these statues. Stand just out of range of it's beam and shoot it's eye to defeat it. Then pull it out of the way and enter through the door behind it. An old Goron leader will give you the last key shard.
find all three goron elders in different parts of the dungeon and they will each give you a separate piece and tell you how to find the next one.
Death Mountain
it is the goron mines aka fire temple. it is in death mountain.
Goron Mountian, named Death Mountain in this game, is at the upper left corner of Kakiriko Village.
The gorons can be found on Death Mountain in the Ocarina of Time, Twilight Princess, and the Majora's Mask. Gorons can be found in Mountain Village and Snowhead in Majora's Mask.
you go to the goron mines and finish it at the end you will meet darbus
teleport with Minda to get the flaming rock on death mountain :P
Go to Death Mountain and bring the lava rock to the throne room.
Go to the store owner lady in Ordon village or to the store at the hot springs at Death Mountain.
put on your iron boots and walk over or around it.
Use Minda to warp the giant lava rock from Death Mountain to the frozen part of the lake.
If you mean the Mirror Shards, none are in Death mountain. (they are in the temple of time,snowpeak and the city in the sky) The fused shadows? however one is int he death moutnain, just mak your way through the temple, and when you beat the Twilit att he end, you get the fsed shadow !! - Simples ;)
What kind of question is that? The Gorons are these weird, yellow, rock guys who live on Death Mountain. They like Sumo wrestling, and hot spring water.
