Spoilers Ahead on Age of Resistance skekLach.

skekLach was the Skeksis Collector and counterpart of urSen the Monk, whose position was to collect the tightening of Offerings of the Gelflings Clans every year, along with skekOk the Scroll Keeper. He had a jaded persona, never finding any form of enthusiasm unless someone was harm, though he was not the instigator of said harm just a bystander. He was much shorter than the Scroll Keeper and was recognizable for his grotesque pustules and allergy problems, always speaking in wheezing and hacking voice.

During the battle of Stone in the Wood, skekLach was killed when Deet redirected the Darkening attack from the Emperor's staff, exploding in a pile of Puss. When the Skeksis return to the Castle, both skekOk and skekEkt were deeply affected by his loss and mourned him.

skekLach was first introduced in Legends of the Dark Crystal, and his design and personality where very different: plotting to steal essence from the Emperor while extorting the Scientist as well dealing with the power hungry Chamberlain's attempts to defeat him. He was more menacing looking and had a mechanical left arm, a scar and a glass eye, his position of Collector was more different since he was in charge of the Garthim Raids along with skekUng to collect prisoners and their treasures some of which he collected.
