Oh dude, Darligrov is one of the five most powerful words of power. His family line has that Armstrong thing of "Passed Down For Generations!" 

The connection to the rings is rarely mentioned due to the fact that nobody asks, but the rings are part of his family's Flag. Yes, flag. High breed Pundambayan families equate to royalty, they've got flags and the like.

It's pretty deeply lodged in his psyche, in life he was proud to be born with the ability. 

The five words are: 
Darligrov (Dahr Lih Grove) - Obviously his former word and now his nephew's word.
Jaggar Roh (Jae Gahr Row)- The word spoken by his daughter and father in law. Shaped energy beam projection.
Kagrackahs (Kah graah kass) - Metal Plate generation. Surprisingly useful.
Toganakun (Toe Gaenae Koon) - Explosive pellet projection. 
Soho (Sew Hoe) - Creates a field of absolute silence. Wielded by Drom Fortin Inar.
