 Lowering Temperatures
You need to be at least Level 79 to receive this quest.
You need to be at least Level 73 to turn-in this quest.
Combining all the information reveals that the water processing devices can be found at various locations around the Boiling Lake where there are features that can't be destroyed by a thousand years of history.
You must have seen the curved piping near Byalant. They are very old and I think they were there before the Guardian factory was even built. We estimate that they were part of the processing device.
The ancient civilization uses mysterious runes that contain a natural energy. After analyzing the diagrams in the book, it seems they included five key elements, a Frost Rune, Activation Rune, Disenchant Rune, Starter Rune, and Operational Medium. We need to find enough of these elements and use them on the proper device in order for it to work.
The only thing is that these runes are scattered around and I'm not sure quite where. The No. 89-X Punishers and No. 89 Digger Punishers, which are constantly digging around Boiling Lake have some. The wreckage resting on the bottom of the lake is also a good place.
We have some more information about how to perform this quest but recognize you might want to try it on your own before we tell you the secret...
|First you need to find the runes. Kill No. 89-X Punishers ( Frost Rune, Activation Rune) and No. 89 Digger Punishers ( Disenchant Rune), and look on the lake bottom for Lake Remains ( Starter Rune, Operational Medium).
Once you have the five runes, install them as follows:
The game provides some further information that may, or may not, actually help...
|Research the curved piping and confirm which energy they used. Then collect enough Frost Runes, Activation Runes, Disenchant Runes, Starter Runes, and Operational Media to install them. Don't forget that not only do you need to use the correct amount of runes, you also need to use them on the right device to achieve a result.|

|Can you here that rumbling sound? The water processing device has already been activated. We don't know how long it will run, but at least it will give us enough time so that the Alliance army can pass through this scorching area.
You can go back and report to Master Template:Npclinkh. We need to make sure we record this unique experience and give it to headquarters.
FYI Do the frost, Activation and then the disenchant rune in this order then the starter (need 2) and last Operational Medium (need 3 mainly from the lake remains). Also, the game does not remove your leftover runes after completion. They have no further use, so you may descard them.
