Gadra

Gadra was introduced as the Imperial Court Magician of the Eastern Empire and is the master of Razen. He has lived for more than a thousand years—every time his life was about to come to an end, he would undergo the secret ritual he invented—the mystic art of 'Reincarnation'—in order to rewind his lifespan by being reborn as a baby somewhere else in the world.

Appearance
Gadra has the appearance of an old man with very long white hair and beard.

Personality
He has been described by Rimuru as a born egotist and that he has no relation to things like loyalty. However, he appears to value people close to him a lot, so much that avenging Adalman's death more than a thousand years ago is the sole reason that he allied himself with the Eastern Empire.

He is also an opportunist that's quick to adapt to changes. When he learned that the Clerics of the Seven Luminaries (his subject of revenge) were eliminated, and Tempest turns out to be a much greater threat than expected, he defected to Tempest without hesitation.

Finally, his other defining trait is his fascination with magic. Every time he reincarnated, he would read the treasured books of each royal palace library and build up his knowledge. He held grudges against the Eastern Empire for phasing out his Magic Corps in favor of the Armored Corps. Despite this, he is very open-minded and is always keen to listen to ideas raised by otherworlders.

Background
Gadra was a close friend of Adalman when he was alive. As Adalman was killed due to nefarious schemes concocted by the Seven Luminaries, Gadra performed his Reincarnation magic in an attempt to revive him. However, because the ambient miasma had tainted his soul, Adalman was reborn as a wight. As a result, Gadra swore revenge against Luminism and the Seven Luminaries, and allied himself with the Eastern Empire.

Throughout his few hundreds years of service in the Eastern Empire, Gadra had been ushering the Empire to wage war against the west. He is one of the survivors of the previous Veldora subjugation operation.

He is also the one who appealed to the emperor about the practical use of otherworlders. As a result, otherworlders have been receiving special treatment in the Empire, and far more had gathered there than any other nation. Research upon their skills and knowledge raised the Empire's military technology to a level that surpassed all the other nations in the world.

Story
Before the Empire began its invasion, he sent Shinji Tanimura, Mark Lauren, and Zhen to Tempest as spies. Meanwhile, he personally travelled to the Farmenas Kingdom, intending to convince Razen to submit to the Empire. Much to his surprise, he learned that his subjects of revenge were eliminated, and Tempest turned out to be much more powerful than he expected.

Judging the Eastern Empire's invasion to be a lost cause, he defected to Tempest alongside Shinji and his team, and has been given the guest treatment since. Gadra ended up as the new guardian of the 60th floor in Ramiris' Labyrinth and became a hidden boss besides the Demon Colossus.
