Sangua is a world of bones and dust with a lake of blood being drained by the demons, resembling Sethekk Hollow on Draenor. When Legion Blood Drainers are destroyed, something stirs beneath the surface. Occasionally tentacles will erupt out of the ground as well.
In Legion an Invasion Point connects Argus to this target location.
Manifestations of congealed plasma inhabit the pool of blood in the invasion point. However, whether or not these creatures exist as a product of Legion tampering is unknown.
Large rib bones and spines indicate the current or past presence of giant vertebrate.
Where to start?

Also, this game then elicits more interesting questions. For instance, how Illidan Stormrage became so hated or where the Scourge started.
