What is it called when you namedrop something insignificant and make it significant? - Taric Lore

As he approached the summit, Taric was challenged by a seemingly neverending myriad of conflicting realities, each warped existence offering a new, horrifying vision. Taric experienced the infinite fates that could befall those who had no one to protect them in their times of crisis. He saw the** Alabaster Library** engulfed in pitch and flame, and still he dashed into the roiling inferno to retrieve the poetry of Tung. He screamed in rage as the Frostguard ran the last dreamstag off a blind cliff, and then leapt into the abyss himself in a desperate attempt to save it. Before the ebon gates of Noxus, Taric slumped to his knees at the sight of Garen’s shattered body chained aloft as a warning. Between Taric and his friend stood the sum total of Noxus’s might.

So in this passage of Taric's new lore, Riot name drops 'Alabaster Library', 'poetry and Tung', and 'dreamstag'.

All of these things are insignificant mentioning of things that sound cool. Like it has no meaning because we aren't told what these things are except at face value but they're supposedly important. I'm not sure what this is called.

Is this part of the 'Rule of Cool' trope?
