The Crystalline Lake could not be located within the heart of the Blood-Drip Jungle. In fact, if one measured the Blood-Drip Jungle, and its depths, one would realize that the Crystalline Lake only signaled transitioning from the outermost perimeter of the Blood-Drip Jungle to the initial inner reaches of the forest.
The danger one may've faced up to now would then begin an evolution.
So, to those that did not find the Blood-Drip Jungle as dangerous as it may have previously been portrayed as, perhaps not the Crystalline Lake itself, but soon after encountering the Crystalline Lake, one was sure to pick up a whiff of a certain scent.
This scent...
Whether it be within the depths of the Crystalline Lake, or past the lake and deeper into the forest, it was omnipresent.
Naturally,
This was the scent of death.
