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 octopus, covered with crooked text tattoos. He has two pupil-less, blue-white murky eyes and his skin color is deathly pale like a corpse. He wore a black cloak decorated with silver accessories and several loosely-fitted belts.

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 Smaragdina 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. His creations Albedo and Nigredo embodied respectively these two hobbies.

Background
According to Momonga, he was quite versed in the knowledge of occult lore.

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, Ainz is impressed by Tabula’s work, as he manually placed many Carrion Babies there. He wonders how much money he 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.

Abilities and Powers
In terms of pure destructive power, he is a stronger magic caster than Momonga.

Trivia

 * In the Web Novel, he is the creator of CZ2128 Delta.
 * His name is a reference to the Emerald Tablet.
 * He is responsible for the design of Treasury security systems.
 * Pandora's Actor transformed into him when he was first introduced.
 * His appearance is reminiscent of the Illithid, also known as the Mind Flayer, from Dungeons and Dragons and sources that draw on it for inspiration. As is the racial description, seeing as Illithids in most D&D inspired settings are described as creatures that feed on the brains of other creatures (most notably other races).
