Kobolds.
Kobolds also 'worshipped' death. To the kobold survivors, death was an inevitable stalker to be slowed down if no contained. This is why some kobolds appear to be obsessed with traps; they intend to delay or defeat death's many avatars by trapping them and hindering their progress. Over centuries, this has mutated. In some groups, creating traps has gone into creating mechanical devices, both functional or aesthetic--the more complex the better.
Before the end of the world, kobolds had been created as servitors to the old dragons. When those dragons died and the kobolds lived, their belief and loyalty was shattered. When the new dragons took over the world, some saw this as punishment for abandoning the old ways and tried to throw themselves back into service--deeply confusing the new dragons, who put them to work as menial labor and nannies to their eggs. When the dragon nations finally lost, the kobolds were ALL seen as Quislings by outsiders, even the ones who never bent the knee or rebelled. It has been centuries and kobolds still labor under the concocted stereotype of sniveling cowards who will serve anyone strong.
The truth is, most kobolds have, until recently turned their backs on society and tried living their lives on the fringes and explicitly avoiding the cruel and corrupt trappings of contemporary society. Ironically, as the world's view on dragons has softened, kobolds are now seen with (unwanted) pity, which has prodded some kobolds to decide to go out and set the record straight, setting out to become brave adventurers, prominent bards, and even villainous masterminds (basically straight up supervillains and mad scientists).
With all the chaos this brings into their lives, a lot of kobolds want even harder to be left alone, putting their trapping traditions to work keeping lookie-loos away from their homes out of shear exasperation.
