Introduction and Guide

Civmar is a tower in Northwest Sepharia. Under the land, inhabits a terrible evil that was sealed away by a witch and a necromancer long ago. To obtain the
mark, you must unseal this evil and destroy it. On the main floor of the tower is a library. The description will note that documents are scattered around.
Search in this room to obtain a book. Look at the book to see it now wants you to read margins. Look margins.
The book:

Inchet, a common name given to an ancient beast which was once ... Therion
in the most ancient of times which have ... lost to our ... histories.  This
terrible beast once held all of Oceanus Ingenii in an unchallenged grip ...
terror and destruction.  ... ... of this beast it is said ... have swallowed
sailing vessels whole with gaping jaws and teeth as sharp as diamonds.  The
... state that this evil creature is a child of pure chaos and born at the
beginning of the world within the great whirlpool known as the maelstrom. 
This monstrous beast grew so infamous that even the most stalwart of sea
captains feared to sail ... ... people cried out for ... ... ... something
... the terrible ... and a great fleet of war ships ... constructed in ...
... of nations which had never before ... ... to work as ... A great battle
at sea which lasted over a week as the fleet of war ships pursued and ...
the dreaded monster.  Inchet, was beaten at the last and fled into the caves
and tunnels which delved deeply into the roots of Sepharia.  The creature was
pursued into the tunnels where many valiant warriors fell to the dread beast
... in the darkness.  At the last the great witch Thirasael ... and ... ...
Ataxia ... ... ... ... a binding ... to seal ... Inchet for all of ... and
hold ... in the ... The great ward was known thereafter as Therion's Array. 
There the terrible beast is held captive and cursed to reincarnate upon ...
death with the hope of escape ... out of reach.

On the bottom floor of the tower is an underwater diamond shape of rooms. In each of the north, east, south, and west corners you can look mural.
The murals read as such:

Besrhien Asche Nohziel Tahet Moxepazia.  - north
Derahlse Baln Jedahtexoi Tahl Gepsanaoh  - east
Ezorethi Vlore Plorien Vahst Aptheniel - south
Cettapal Et Hezteprion Vixi Kahusaela - west

In the center of this underwater chamber, you can search down. Upon entering this room for the first time, you will be asked a riddle. If you left
and re-enter, the riddle is not repeated. So say anything in this room to take some damage and get a different question. You must answer 3 riddles correctly
using the information provided in the margins, around the tower, and the mural. This must be done 3 times to receive a key which will lead to a 3x3 square.

Example questions include:
1. An ominous voice whispers inside your head, 'Spawn of most vile nature, this swirling darkness was the cradle.' - Maelstrom'
2. An ominous voice whispers inside your head, 'A shapeshifting creature sired an ancient witch, but where was he from?'
3. An ominous voice whispers inside your head, 'Name the necromancer of untold power who sealed away the beast.' - Ataxia
4. An ominous voice whispers inside your head, 'A tattered old book was translated by a scholar, read the margins and speak the sixth word from line five.' - Jaws
5. An ominous voice whispers inside your head, 'A tattered old book was translated by a scholar, read the margins and speak the first word from line one.' - Inchet
6. An ominous voice whispers inside your head, 'A tattered old book was translated by a scholar, read the margins and speak the second word from line six.'
7. An ominous voice whispers inside your head, 'A tattered old book was translated by a scholar, read the margins and speak the seventh word from line fifteen.' - Valiant
8. An ominous voice whispers inside your head, 'Long ago murals were carved with the serpents image, and a binding phrase to hold it forever. Speak that phrase inscribed upon the mural of the west.'
9. An ominous voice whispers inside your head, 'There are murals that were carved long ago, upon each a phrase is written. Speak the phrase of the north.'
10. An ominous voice whispers inside your head, 'Long ago murals were carved with the serpents image, and a binding phrase to hold it forever. Speak that phrase inscribed upon the mural of the north.'

After obtaining the key and making your way into the 3x3 square, you will see 2 locked rooms in the center of the squares and Lord Ataxia to the south. Kill Lord Ataxia for his skull.
The locked rooms can be magic unlocked. Up is an altar where you can put the skull of Ataxia to get a key for the down.

You put the skull of the lich-lord Ataxia in a sacrificial stone altar.
The skull of the lich-lord Ataxia crumbles within bowl of the altar leaving behind a pile of bone dust.
The dust is drawn into the bowl of the altar turning a dark red as the ancient blood sacrifice mingles with it.
Something heavy clatters to the floor as it is disgorged from a hidden compartment within the altar.

The down will have 2 dizzy rooms, the first down, and the next down with the witch Thirasael Moonblood. She will aggro upon entering her room and form with a captain to fight you. The captain
doesn't take damage, so focus on Thirasael. When she speaks, she will instacast certain spells or start to cast a shield blockable spell. I presume this is firebolt. So if you see her talk and
start casting, don't cast the next round. It is recommended to bring calm herbs and mutini herbs for the dizzies. After Thirasael, there is a final down that will open to a CPK room with Inchet.
Detect invisibility is required to see it. Inchet does not aggro upon entering the room. You can dispel his haste and invis. He does pierce damage, has a ton of health, but will not cast spells.
Upon landing the killing blow, you will be rewarded the mark of Sepharia.
