Lowering Temperatures

After obtaining the Ancient Runes, activate each Water Processing Device.

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 [242641|Frost Rune], a [242642|Activation Rune], a [242643|Disenchant Rune], a [242644|Starter Rune] and a [242645|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 [<S>107710|No. 89-X Punishers] and [<S>107717|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.

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 [122341|Kargath Duran]. We need to make sure we record this unique experience and give it to headquarters.

Research the curved piping and confirm which energy they used. Then collect enough [<S>242641|Frost Runes], [<S>242642|Activation Runes], [<S>242643|Disenchant Runes], [<S>242644|Starter Runes] and [<S>242645|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 the on the right device to achieve a result.

You can get runes from the [<S>107710|No. 89-X Punishers] and [<S>107717|No. 89 Digger Punishers]. The [122354|Lake Remains] is also a good spot to dig for clues.
