Rakshasa

The Rakshasa are a faction of Nexus Aetherbeasts from various breeds that are the followers of Basilard. Rakshasa are recognized by their golden eye color, a visible side effect of the Mortal Shell technique.

Corruptors and deal makers; the Rakshasa serve as an analogue to the way demons are often portrayed in other settings (with 'demon' being used to refer to corrupted spirits within the Clockwork Tower). While there is no requirement for a Rakshasa to be explicitly evil, the use of blood alchemy and diabolism does not lend itself to those with moral integrity. This group are not a specific breed of creature, but rather a philisophical and academic faction: Particular Rakshasa can be from any Aetherbeast breed - or even similar creatures such as fey.

Blood Alchemy and Diabolism
The Rakshasa are practitioners of the sciences of Blood Alchemy and Diabolism: the Mortal Shell technique itself being a form of Blood Alchemy (and actually requires a living mortal to be sacrificed for the creation of each new body).

The Mortal Shell Technique
Learned from Basilard himself; the Mortal Shell technique allows a aetherbeast to create and live inside a mortal body - preventing them from expending aether on simply existing. While using a mortal shell the Rakshasa is able to accumulate free aether and prevent the slow burn out of their own body: in this way they increase their own natural longevity while also having spiritual potential nearing that of a human.

The use of this technique makes the Rakshasa nearly immortal as well as giving them the ability to be potent mages. The use of this technique does, however, mark them with golden eyes.
