Trinity

Trinity (トリニティ) was a top Guild that existed in YGGDRASIL.

Background
Trinity was originally a guild formed from three of the top guilds that aimed to oppose the 2ch Alliance. Eventually, it rose to become the top guild in YGGDRASIL.

The Men in the Kingdom Arc
Whilst Sebas Tian and Demiurge argued over the fate of Tuare, their argument made Ainz Ooal Gown reminisce of his time with his guildmates. He remembered a moment during one of their meetings, they plotted to reclaim the Seven Hidden Mines from an unknown guild who use the World Item, Ouroboros on them. Punitto Moe suggested leaking information to Trinity and then 2ch Alliance about the mine's special relationship in creating Caloric Stone.

This way, it can stirred up a conflict from within the two guilds. Punitto Moe believes that Ainz Ooal Gown will be able to strategically strike at Trinity and 2ch Alliance once they are in a weakened state after the fighting.

Strength
Trinity was an alliance of three guilds and was ranked as the number one guild in YGGDRASIL.

Below is a list of guilds that founded Trinity:
 * The Father
 * The Son
 * The Holy Spirit

Trivia

 * The name was based on the Christian doctrine that holds God is three on-substantial persons, which its founding guilds are named after.
 * So far, it is the only guild known to have been formed through other guilds.
