Overlord F/GO collab? It's more likely than you think.

I started playing FGO recently, so imagine my surprise when I found that they were doing an Overlord campaign collab... Time to blow your Jalter savings, plebs!

EDIT: Although, seriously, job well done, cirnopedia. I really appreciate the attention to detail.

The Undead King

The Dark Warrior

The Lizardman Heroes

Class: Lancer

Profile: One of the NPCs created by the 41 Supreme Beings, she is the Guardian of the 1st to 3rd Floors of the Great Underground Tomb of Nazarick. She is a Vampire, but possesses the appearance of a young girl, and she is the strongest of the Floor Guardians in single combat. Possessed of special tastes and hobbies, her heart is devoted to Ainz.

"I am the Floor Guardian Shalltear. Both my body and loyalty belong to Ainz-sama!"

Noble Phantasm: Crimson Valkyrie: Battle Maiden of Fresh Blood

Effects: Extremely high damage to a single target and restores a great deal of own HP (effect increases with Overcharge) and increases own ATK for 3 turns (effect increases with Overcharge).

Class: Shielder

Profile: One of the NPCs created by the 41 Supreme Beings, she is the Guardian Overseer of Nazarick, and the highest-ranking of all the NPCs. Easily worthy of the title of "world-class beauty", part of her is filled with deepest regret thanks to a setting Ainz made to part of her backstory...

"I am the Guardian Overseer Albedo. I pledge my utmost loyalty to the Supreme One."

Noble Phantasm: Walls of Jericho: Great Wall of the Ancient City

Effects: All allies gain Invincible status (1 turn) and increased DEF (5 turns and charge NP gauge every turn (5 turns, effect increases with Overcharge)
