Solarus

One of the oldest beings in the Universe, Solarus and his
Leviathan brethren manifested at the Dawn of Creation.  His true origins
are unknown, and it is speculated whether he is a sentient black hole, one of
the aberrations created by Lucifer’s tampering with the Act of Creation, a
material shard of an Outer Beast which found its way into the Universe, or some
other undreamed of possibility.  Since then Solarus has traveled from one
end of the Universe to the other, consuming worlds and suns, battling Gods and
Devils, and blah blah.  Because of his great age and power he believes he
is superior to essentially every other being across all the planes of the
existence.
While the glowing giant is the more popularly known form of
Solarus, in order to travel across the expanse of space he manifests a moon
sized shell which acts as a form of space ship for him.  Intrepid
adventurers are able to enter this shell, but upon doing so discover a
labyrinth of arcane technology and terrifying dangers which they must navigate
in order to find Solarus himself sitting on a great throne at the center. 
When he reaches his destination he is able to manipulate the shell in any form
he desires, either dismissing it to another dimension or breaking it apart to
use as countless weapons or tools.  Many of his most powerful attacks
entail him manifesting parts of his shell and using them to attack opponents.
== Powers and Abilities ==
=== Elder Force ===
As a Leviathan, Solarus’s abilities are fueled by an
enigmatic power called the Elder Force.  Functionally similar to the Grace
of Gods, this power grants him effective omnipotence and omniscience enabling
him to accomplish practically any effect he pleases.  Unlike the power of
Gods, the Elder Force is not self-perpetuating and must be replenished by
consuming vast amounts of life force.  
Nigh Omnipotence: Using the Elder Force, Solarus could
achieve virtually any effect he desired. 
Telekinesis: Using his mind, Solarus was able to move and
influence objects from across the expanse of space. 
Telepathy: By extending his consciousness across space,
Solarus could read the minds of his countless subjects and even control the
minds of entire populations. 
Teleportation: Solarus could appear anywhere within the
range of his power.  He could also forcibly teleport others wherever he
wanted provided he was more powerful than them. 
Transmutation: This power allowed Solarus to alter matter or
create it from nothing. 
Omniscience: By concentrating on something Solarus could
instantly know anything about anything or event unless he was being blocked by
a greater source. 
Devour: As a Leviathan, Solarus’s powers are dependent on
his consumption of life force.  To this end he is able to draw it in
through either his mouth or hands, or on a planet wide scale by manifesting the
tendrils of his shell and driving them into the ground or some other
sufficiently large target.
== Trivia ==
- Solarus is either directly responsible for or knows who is responsible for giving Thuro the Endless Curse.
- Solarus was bitter enemies with King Rao and they clashed many times even after the Cataclysm. It was Thuro's revelation that Rao had obtained the Bloodstone that prompted Solarus to give him the location of Ultima.
- He recognizes sarans as demons and refers to them as "lowspawn." He also detected Cain's latent Oversaran power when he says that he recognized a "devil" hiding in the last saran that he met.
- When he went to see Solarus to learn the location of the Dragon Road, Thuro opted to bring Kara with him. While he joked it was because he needed muscle and she was the only one who could fit with him in a Space Pod, he actually chose her for several reasons. For one, Leviathans have a tendency to overwhelm the senses of even the most powerful mortals. Owing to their demonic nature, sarans are largely immune to this. Also, Thuro counted on Kara's tendency towards airheadedness to miss the context of anything incriminating Solarus might say about their past relationship. Indeed Kara was too distracted by their surroundings to pay much attention to what Solarus was saying and what he did say was a bunch of stuff she didn't understand. Even Solarus mocked her as "empty headed."
