Tabula Smaragdina

Tabula Smaragdina (タブラ・スマラグディナ) is a guild member of Ainz Ooal Gown and regarded as one of the Forty-One Supreme Beings by the NPCs of the Great Tomb of Nazarick. He is the creator of Albedo, Nigredo and Rubedo.

Appearance
Tabula's appearance is that of a humanoid with a head resembling that of a distorted squid. He wears a shiny, form-fitting black leather outfit studded with silver jewelry and several belts wrapped around it. His black cape was also closed in front of it, as if to conceal its body.

While so, the right side of his head was shown to be half-covered in a twisted, tattooed letters. He has two cloudy pupil-less, blue-white eyes as well as six twitching tentacles that are sprouted from his mouth dangled down to his thighs.

His skin was like that of a corpse, with purple blotches amidst a ghastly white color. He was covered in some sort of sticky slime that gave off a bizarre sheen. Additionally, webs of skin grew between the long digits of its four-fingered hands.

Personality
Tabula Smaragdina has a strong personality, in various ways. During normal discussions, he would be coherent. However, as the talk became more in-depth, various parts of his personality that are hard to associate with would begin to surface.

Tabula has two passions: "gap moe", which is the cute contradiction between the actions of someone and his or her usual character, and horror films, of which he has an extensive knowledge, from the classics to the latest, that surprised even his fellow guild members.

Background
Tabula Smaragdina attends the weekly clan meeting for Nine's Own Goal meeting. He is intrigued by Nishikienrai's news of a unexplored dungeon, and is surprised that it was located in the Grenbera Swamp as many did an aerial reconnaissance of the place and found nothing. He hypothesizes that the Great Tomb of Nazarick could only be found on foot. After the Clan is to be reorganized as Guild, Momonga is designated as Guildmaster. Tabula confers with Punitto Moe and Bellriver, each sending emails to Momonga stating that no one else was suitable else the Guild would tear itself apart. Once Momonga accepts, the clan members attempt to create a new name. Tabula suggests Knights Templar, however it is rejected like many others until the name Ainz Ooal Gown is decided.

Later Tabula joins his guildmates in an expedition to the Great Tomb of Nazarick. While in the marching as a rear guard in the swamp, he attempts to discern where the name Nazarick originated in human mythology but was unable to come to an answer. At the doorstep of the tomb, he is hesitant to divide their group into parties, wanting to wait until they got deeper into the tomb. The Guild then by majority vote agrees to Tabula's suggestion and continues on. Tabula turns out be correct as it is discovered that the tomb is a simultaneous attack dungeon. At that point he is assigned into a team and enters the depths of the tomb.

Tabula and his group manages to make to the last level where Momonga and his group successfully kill the Asura. Tabula celebrates with his Guild at the conquest and the acquisition of the Great Tomb of Nazarick as they take a photo of their victory.

According to Momonga, Tabula Smaragdina was quite versed in the knowledge of occult lore. Additionally, he has a lovable taste for watching horror movies. Based on his knowledge and taste, he would used it to help him on the creation of his own NPCs. His creations Albedo and Nigredo embodied respectively these two hobbies.

On the other hand, Tabula had a hand in designing about 20% of the smaller mechanisms throughout the Great Tomb of Nazarick. His abnormally intricate designs consumed much of Nazarick's free data capacity, which caused the other members to complain about being unable to indulge themselves. Thus, he took responsibility for his actions and paid for many cash items to expand said data capacity.

The Undead King Arc
Prior to YGGDRASIL's silent shutdown at the end of the game, Momonga recalls all the good times the members of the Ainz Ooal Gown including Tabula Smaragdina. In his lamentation of his fellow guildmates' departure a few minutes before him, the Great Tomb of Nazarick and all of its NPCs were transported to the New World.

When Ainz says that he feels bad for altering Albedo’s setting and tarnishing Tabula’s creation, Albedo only replies that Tabula would definitely give his blessing with the feelings of seeing his daughter off marriage.

The Bloody Valkyrie Arc
When Ainz and Albedo visits Nigredo in the Frozen Prison, he is impressed by Tabula’s work, as his guild member manually placed many Carrion Babies there. Ainz wonders how much money Tabula must have spent in the end, as he configured many monsters.

Ainz reminisces about Tabula one more time when he enters the Treasury, saying he was a perfectionist. He reminds that Tabula was one of the people responsible for designing Ainz Ooal Gown’s mechanisms. He also remembers that he wasn’t a bad person and had a strong personality, in various ways.

The Ruler of Conspiracy Arc
After Ainz gave the Book of the Dead to Fluder Paradyne, he showed him some page of its lore and then mentions his guild member, Tabula Smaragdina. In particular, Ainz thought that if Tabula was present with them right now, he would be able to explain the meaning behind this book's lore to Fluder.

The Craftsman of Dwarf Arc
When Ainz shared with Gondo Firebeard what he knew about runes, most of the things he mentioned were what he learned from his friend Tabula. However, Ainz had forgotten many things from what he learned from Tabula.

Quotes

 * (Spoken his hypothesis after Punitto Moe's): "Perhaps the Great Tomb of Nazarick only appears to people who've traversed the poison swamp on foot? Or perhaps it's only visible under a certain altitude."
 * (To his Guild Members about their unnamed guild): "If that's the case, how about the Knights Templar? After all, Touch-san is kind of like Hugues de Payens. Well...though we are missing one person."
 * (Disagreeing with Punitto Moe): "Hang on! Don't you think it's a little early for that? I think we should stay in our current movement parties and go as deep as possible before changing up. If we break up now, we'll need to dispel our whole-party spells...In addition, we should be able to go through the dungeon in this state, with only a little more trouble with the mid bosses, right?"
 * (To Momonga): "Ah, Momonga-san, this looks like a simultaneous attack dungeon. And it looks to be the hardest kind, the sort that needs five parties to progress. Then again, we should probably be glad it's not one of those dungeons that needs 36-man parties (a legion) and allows two guilds to cooperate on invading them. Those are just crazy."
