Sefut

Sefut, referred to by Gollum as the Frail Man, was a slave of Mordor working in the Black Pits. Sefut appears only in The Lord of the Rings: Gollum and as such, is non-canonical.
==Biography==
According to Logri, Sefut was once a great king of a realm to the south of Mordor. Eventually however, he was taken from his realm and became a slave in Mordor working in the Black Pits alongside other slaves such as Logri and Darimon.
Sometime later, after Gollum was thrown into the Slave Barracks, Sefut taught him how to do the many menial tasks required in the Black Pits. Eventually, Sefut tasked Gollum with stealing some plans which they used to blow up a bridge. However, Gollum was caught by Orcs and brought to Ileth. In a desperate bid to avoid a cruel fate, Gollum attempts to claim that either Sefut or Logri forced him to steal the plans.
If Sefut is blamed, he is thrown into a cage and taken to be executed. However, his execution sparks hope within the other slaves. Despite this, if Logri is blamed, Sefut laments not being able to make his own death have meaning.
