Vorago is a construct of anima.
His prime directive currently is to protect the deep places of Gielinor (presumably to protect the plane's anima).
At some point in the past, he rampaged on the surface of Gielinor before being defeated with the maul of omens.
Oh, and he can channel significant amounts of Gielinor's anima into himself in order to vastly increase his own strength and can unleash this power in a large blast.

Araxxor/Araxxi is an Araxyte. Although similar to spiders, Araxytes differ from spiders in that they have only 7 eyes. Equally so, the Slayer helm does not recognize them as spiders, indicating some notable difference to spiders.
Araxxor/Araxxi and other Araxytes only live in the Araxyte hive on Gielinor. This reflects the idea of them preying on Vampyres (staying close to their prey).
Araxytes purportedly favor preying on Vampyres, which would mean they have some method of circumventing the Vampyres' natural mind reading abilities.
Araxxor and Araxxi are mates.
Based on the boss fight, the continued survival and security of the hive appears paramount to the Araxyte. Araxxor defends the hive from the initial intrusion before allowing Araxxi to consume him should he fail so that she is more capable of repelling or killing the intruder.

The Chaos Elemental, as the name would suggest, is an elemental of the runic element of chaos.
Considering it drops ancient warrior equipment, it is likely that the elemental's creation and composition has something to do with the beings killed by the blast that turned Forinthry into the Wilderness (much like the only other source of this equipment: Revenants).
The Chaos Elemental appears to have some precognitive capabilities, but is incapable or unwilling to communicate this information in a straightforward method.
Given its location and moniker, it is likely a result of or was empowered by the Wilderness's creation.
