Blood of the Void

Cartography Report
Malathier, having been formed from the drop of the first rivers falling off of Terra, found that some of his essence had been instilled into the surrounding waters of the Nether. Although it is said to sit in the lower reaches of the Nether, unused, sometimes this black liquid seeps up into the Terra. When men find this and bottle the liquid, unpredictable (and often deadly) results can be expected.
