Llaekh-ae'rl was a martial art practiced by the Romulan people. The name translated to Federation Standard as "laughing murder". This combat form required the user to root themselves to the ground and control their movements. N'alae was an expert in this art and attempted to teach it to Ael i-Mhiessan t'Rllaillieu, however, her fire proved to be the better of her which meant she never mastered it. (TOS - Rihannsu novel: My Enemy, My Ally)
