After being given a moonblinked Eglantine and another owlet by Kludd, Allomere returned to the Great Ga'Hoole Tree and told the Guardians the Pure Ones plan, which made the Guardians decide to fight them. However, this was part of Metal Beak's plan and when the Guardians arrived

LADY AND THE TRAMP GUARDIANS VS PURE ONES

the device was activated and the Guardians were pinned to the ground with its power However, Soren and the band arrive to save the Guardians (after Eglantine revealed to him that Kludd had moonblinked her and gave her to Allomere).

A worried Eglantine looks on before telling Kludd that she misses their parents, to which Kludd replies that she shouldn't worry as she is with him and the Pure Ones appreciate them Eglantine pleads with Kludd to come with her to find Soren, to which Kludd (who has grown to hate Soren), tells his sister to forget about Soren

You have to stay awake, Eglantine, or the Pure Ones will moon-blink us

You have to stay awake, Eglantine, or the Pure Ones will moon-blink us

He longed to be appreciated and respected (which he found when joining the Pure Ones) and boasted about Tyto superiority. One day, after being taught branching by Noctus, Kludd and Soren fall from their tree (after Kludd got annoyed with Soren and shoved him for talking about his hero Lyze of Kiel)

which makes Kludd reply that Soren doesn't know him at all. When launching at Soren, Kludd breaks his wing and dangles above the fire. Kludd pleads for Soren to help him, but when Soren tries to,

to stop him from destroying another owl's life as he did to Kludd. Following Metal Beak's death and the Guardians' victory, it is revealed that Kludd (now with red Pure One eyes) had survived the fire and comes across Metal Beak's body and gazes down at his mask, possibly taking it for himself.

, before screeching at Grimble, giving Nyra time to overpower the older owl and throw him to his death. During this, Soren and Gylfie escape to find the Guardians. Later when asked by Nyra what he can offer the Pure Ones, Kludd replies that he has his sister Eglantine, who would be a strong Tyto

Pure evil….

Metal Beak's true name is revealed to be Surtr, and it is later explained that he took part in the battle of the Ice Claws along with the Pure Ones against the Guardians of Ga'Hoole. During the battle, Surtr fought and was defeated by a Guardian named Lyze of Kiel

Kludd takes Eglantine from the family hollow (possibly whilst Noctus and Marella were out looking for him and Soren) and brought her to St. Aggie's. He listens to Metal Beak's speech and along with the rest of the Pure Ones present, chants Metal Beak's name

but find him and Gylfie being taught to fly by Grimble (an owl working for the Pure Ones in order to protect his family). Grimble pins down Nyra and tells Kludd to go home with Soren and Gylfie. Kludd once again hesitates, but after seeing Nyra struggling to breathe, declares that he is home

took over St. Aegolius Acadamy for Orphaned Owls (St. Aggie's for short) and would send out his minions to capture owlets (among them Soren and his brother Kludd, who becomes a Pure One) in order to either convert them into Pure One soldiers or make them pickers to pick through pellets

And one thing led to another.
